Effectiveness and acceptability of a multidisciplinary approach in improving the care of patients with advanced chronic kidney disease: a pilot study.

OBJECTIVE: This study aimed at determining the feasibility of conducting a large-scale pragmatic effectiveness study on the implementation of multidisciplinary care (MDC) program for patients with advanced chronic kidney disease (CKD). METHODS: This is a single-arm pre-post intervention design pilot study over 12 months. Participants with an estimated glomerular filtration rate (eGFR) between 11 and 20 ml/min/1.73m2 were screened and recruited at the initial MDC clinic visit and followed for 12 months. Clinical parameters, KDQOL™-36, questionnaires, and interviews were collected, administered, and analysed for enrolment and completion rates, baseline characteristics, implementation fidelity, adherence to CKD interventions, eGFR decline, CKD complications, health-related quality of life, and participants' acceptability of the program. RESULTS: The study enrolment and completion rates were 43.1% (50/116 screened) and 66.0% (33/50 recruited) respectively. The participants had a mean age of 68.5 years (SD9.0) and a mean eGFR of 15.4 ml/min/1.73m2(3.2). After 12 months of MDC program, there was increased adherence to CKD interventions (difference  - 0.6(1.0), 95%CI  - 1.1,  - 0.1, p = 0.02). There was good participants' acceptability of the program with participants being more satisfied with the waiting time and having a better understanding of kidney failure after attending the program. No difference in the eGFR decline noted (difference 0.0 ml/min/1.73m2(5.3), 95%CI  - 1.9, 1.9, p = 1.00). CONCLUSION: Our pilot data suggest increased adherence to CKD interventions and good acceptability to MDC program, albeit no difference in eGFR decline probably because of the small sample size. However, reasons for overall low enrolment and completion rates need to be explored and addressed while designing a future large-scale randomised controlled trial.

Epidemiology and risk factors for cytomegalovirus infection in glomerular diseases treated with immunosuppressive therapy.

AIM: Cytomegalovirus (CMV) infections are associated with morbidity and mortality. We aimed to describe the epidemiology, risk factors and outcomes of CMV infection among patients with glomerulonephritis (GN) who received potent immunosuppressants (IS). METHODS: Single-centre retrospective study of adults with biopsy-proven GN prescribed methylprednisolone (MP), cyclophosphamide (CYC) or rituximab (RTX). Primary endpoint was CMV infection defined by significant CMV antigenaemia (>10 positive cells in 106 cells) or viraemia (>2000 copies/mL). Death was related to CMV if CMV infection occurred within the same hospitalization as death. RESULTS: Ninety-four patients were studied. CYC was prescribed in 65% and MP in 71% of the cohort. Only two patients received RTX and 15 patients received plasma exchanges (PEX). Median follow up was 31.9 (IQR: 13.7, 53.6) months. CMV infection occurred in 13 patients (13.8%) at 1.3 (0.6, 3.0) months from biopsy. Patients with CMV infection had higher serum creatinine [404 (272, 619) vs. 159 (93, 317) µmol/L, P < 0.001] and greater proteinuria [UPCR 7.5, (4.8, 11.8) vs. 4.2 (2.3, 8.4) g/g, P = 0.02] than those who did not have CMV infection. Also, more patients received CYC (92% vs. 60%, P = 0.03), RTX (15% vs. 0, P = 0.02) and PEX (38% vs. 12%, P = 0.01) than those who did not have CMV infection. Two patients had CMV-related deaths. CONCLUSION: Cytomegalovirus infection is common in GN patients receiving potent IS. Surveillance and possibly anti-viral prophylaxis should be considered for high-risk patients.
