Impact of COVID 19 pandemic on patients requiring renal biopsy.

INTRODUCTION

The disruption of healthcare services in coronavirus disease (COVID)19 pandemic was widespread particularly due to lockdown curbs. This study was undertaken to see the effect of this pandemic on subjects requiring renal biopsy.

MATERIALS AND METHOD: Renal biopsies performed during the COVID 19 pandemic between April 2020 and December 2020 (Group 1) were compared with those in pre-COVID period between June 2019 and February 2020 (Group 2). Indication of biopsies, syndromic diagnosis and all baseline laboratory characteristics were retrieved from the hospital records.

RESULTS

130 and 191 patients were biopsied in groups 1 and 2, respectively. Patients in group 1 were younger compared with group 2 (32.55 ± 15.60 and 36.37 ± 16.96 years, respectively, p value 0.038). The mean serum creatinine value in group 1 was significantly higher than in group 2 (3.21 ± 2.08 and 2.68 ± 2.02 mg/dl respectively, p value: 0.023). Group 1 comprises a significantly higher percentage of rapidly progressive renal failure patients (RPRF) (39.3 vs 28, p value 0.046). A higher percentage of nephrotics was biopsied in group 2 vs group 1 (46.9 vs 30.4 respectively, p value 0.008). The treatment protocol remained similar in both the groups. Evaluation of the transplant biopsies revealed a nonsignificant higher number of rejections in group 1 (11 out of 18) as compared to group 2 (5 out of 16), p value 0.100. Combined rejection saw a lesser use of rATG in group 1.

CONCLUSION

COVID pandemic induced restrictive measures could have led to selective high risk patients with RPRF as presumptive diagnosis and higher creatinine values getting biopsied. Higher rejections were noticed in transplant recipients pointing towards the need of establishing a more efficient support system for managing such patients.
