COVID-19 in Patients on Maintenance Dialysis in the Paris Region.

INTRODUCTION: Coronavirus disease 2019 (COVID-19) represents a serious threat to patients on maintenance dialysis. The clinical setting, mortality rate, and prognostic factors in these patients have not been well established. METHODS: We included all dialyzed patients with COVID-19 referred to our dialysis center between March 11 and April 11, 2020. Data were obtained through the review of the medical records and were censored at the time of data cutoff, on May 11, 2020. RESULTS: Forty-four patients on maintenance dialysis with COVID-19 were referred to our dialysis unit during the COVID-19 epidemic. Median age was 61 years (interquartile range [IQR]: 51.5-72.5); 65.9% were men. Comorbidities included hypertension (97.7%), diabetes mellitus (50%), and chronic cardiac (38.6%) and respiratory (27.3%) diseases. Initial symptoms were fever (79.5%), shortness of breath (29.5%), cough (43.2%), and diarrhea (13.6%). Three profiles of severity were distinguished based on the World Health Organization (WHO) progression scale. Forty-one (93.2%) were hospitalized and only 3 were maintained on outpatient hemodialysis. Thirty-three (75%) patients required oxygen therapy, including 15 (45.5%) who were referred to the intensive care unit. Overall, 27.3% of patients died, and 58.5% were discharged from hospital, including only 2 (13.3%) of those admitted to the intensive care unit. By multivariate analysis, cough, thrombopenia <120 g/l, lactate dehydrogenase (LDH) level greater than 2 times the upper limit of normal, and blood C-reactive protein (CRP) >175 mg/l were significantly associated with death. CONCLUSION: A major outbreak of COVID-19 occurred in the Paris region, and spread among dialyzed patients. Our study underscores the severity of COVID-19 in these patients and identified prognostic markers.

[Therapeutic compliance: another challenge for patients on chronic haemodialysis]. / L'observance thérapeutique: un autre défi à relever chez l'hémodialysé chronique.

Poor compliance with therapy is frequently encountered in most of patients with chronic diseases. It increases the risk of morbi-mortality and healthcare costs. Patients on chronic haemodialysis often have poor compliance with treatment. This study aims to assess the level of compliance with treatment in our patients on chronic hemodialysis and to identify the predictive factors of poor compliance with treatment. We conducted a cross-sectional study at the Oujda Hospital in November 2011. The compliance with treatment was measured using a questionnaire: the compliance evaluation test (CET) assessed the compliance with medication treatment and diet. A rate of 85% was retained arbitrarily as a threshold for good compliance with treatment. Patient in a zone of partial adherence had a rate between 57% and 85% while a lower rate (57%) indicated poor compliance with treatment. Different demographic and clinicobiologic parameters were analyzed and predictive factors for good and poor compliance with treatment were identified. Our study involved 101 patients on chronic haemodialysis; the sex ratio was 1.2, the average age of patients was 15.6 years. CET showed that 23.4% of patients had good compliance with treatment, 39.4% partial compliance with treatment and 37.2% poor compliance with treatment. Statistical analysis showed that poor compliance with treatment was associated with a lower socio-economic and intellectual status, with co-morbidities and with long term hemodialysis. Good compliance with treatment was observed in very old patients helped by a third person, taking a reduced number of medications, with a higher intellectual level.

La ponction biopsie rénale: indications, complications et résultats.

Renal needle biopsy (RNB) is the gold standard in the diagnosis of kidney diseases. It is an invasive technique causing several complications, in particular hemorrhagic events. This study aims to evaluate our RNB practice, to update the current understanding of the technique for percutaneous renal biopsy, to assess complications and to determine the prevalence of kidney diseases diagnosed in our region. We conducted a retrospective study between January 2015 and June 2017. Sixty-nine patients hospitalized in the Division of Nephrology at the University Hospital Mohamed VI Oujda having undergone native kidney biopsy were included in the study. The average age of patients, at the time of RNB, was 38.16 ±13 years [12-77 years], with a sex ratio (M/F) of 0.86. Nephrotic syndrome was the most frequent indication for RNB in all age groups. Glomerular kidney diseases accounted for 81% of kidney diseases, divided as follows: extra-membranous glomerulonephritis in 19% of patients, focal and segmental hyalinosis in 18%, lupus nephritisin in 11%, chronic glomerulonephrites in 11%, membranoproliferative glomerulonephritis in 7%, extracapillary glomerulonephritis in 5% shared equally with renal amyloidosis. Four percent of RNB showed diabetic nephropathy. Histopathological examination revealed acute post-infectious glomerulonephritis, minimal glomerular lesion, immunoglobulin A (IgA) nephropathy, vasculitis, tubulo-interstizial nephropathies as well as thrombotic microangiopathy, with an estimated rate of 2% respectively. Five percent of RNB showed non-glomerular disease. Macroscopic haematuria was the main complication observed in our case series, with a rate of 2.8%. RNB is the gold standard in the diagnosis of renal disease. However, syndromic diagnosis enables clinician to identify the most probable renal disease and to guide any emergency treatment.
