Metabolic acidosis in the initial 6 months after renal transplantation: A prospective study.

BACKGROUND: There is limited information about the incidence of metabolic acidosis (MA) after renal transplantation. This single centre prospective study aimed to delineate the incidence and risk factors of MA in the first 6 months after renal transplantation (RTX). DESIGN, SETTING, PARTICIPANTS AND MEASUREMENTS: Patients who underwent RTX between November 2018 and July 2020 were monitored with weekly measurement of serum bicarbonate level for 6 months and those who were diagnosed with MA were evaluated further to characterize the type of MA. RESULTS: One hundred and twenty-five patients were included in the study, 89 (71.2%) of whom developed MA. Seventy-two patients developed MA in the first month, 11 during the 2-3 months and 6 between 4 and 6 months after transplantation. Of the 89 patients, 55(61.8%) had type 1 renal tubular acidosis (T1RTA), 27 (30.3%) had type 2 RTA (T2RTA) and 7 (7.9%) type 4 RTA (T4RTA). Two patient who had T1RTA, subsequently developed high anion gap MA following severe graft rejection. On stepwise multivariate regression analysis, serum creatinine at time of diagnosis of MA [OR (95% CI): 12.02 (1.79 to 80.59), p = .01] and high tacrolimus C0 levels [OR (95% CI): 2.43 (1.0 to 5.90), p = .049], were independent risk factors for MA. CONCLUSION: There is a high incidence of MA in the initial 6 months post-transplant with serum creatinine and high tacrolimus C0 levels being independent risk factors.

Utility and patient acceptance of telemedicine in nephrology.

PURPOSE: There is an increasing burden of kidney diseases worldwide and access to specialist care is limited. Telemedicine, has been relatively less used in developing countries like India. The current study aims to assess the feasibility and acceptance of telenephrology services at our institute, a public hospital. METHODS: A total of 150 patients were selected by stratified random sampling from the list of attendees who had undergone both in-person outpatient consultation and telenephrology consultation. Patient's attitude towards, and knowledge and acceptance of telenephrology services were evaluated. RESULTS: The average age of the study cohort was 42.52 ± 15.1 years. More than one-third (39.3%) of our patients belonged to the lower middle socioeconomic class. The median distance traveled to reach our outpatient clinic was 113.5 km (3-2249 km). Patients reported lost workdays in 54.7% cases. The majority (95%) of patients managed to consult through teleservices successfully. Ninety percent of the patients gave a satisfaction score of 4 (out of 5) or above for their tele-consultation experience. The most important perceived benefit of teleconsultation was the reduced risk of infection (40.6%) followed by economic benefits (32%). The major disadvantage (36%) was the absence of physical examination. A combination of physical and telenephrology services was the option preferred by 84% of the patients. CONCLUSION: In developing countries like India, with the majority of the population residing outside major cities and with limited medical access, telenephrology has a huge potential to provide quality nephrology care to the remotest parts of the country.
