Comparative Analysis of Kidney Transplant Recipients with Severe Acute Respiratory Syndrome Coronavirus 2 Compared with Nonkidney Transplant Recipients: A Largest Single-center Report from the Second Wave of Coronavirus Disease 2019 Pandemic in South East Asia.

Outcomes of severe acute respiratory syndrome coronavirus 2 in kidney transplant recipients (KTR) compared with matched cohort are certainly lacking for different pandemic waves and geographic regions. In this single-center retrospective study of coronavirus disease-2019 (COVID-19) cases admitted during March 26, 2021 to June 7, 2021, a propensity-matched analysis in a 1:1 ratio was performed to compare the clinical profile and outcomes between KTR and non-KTR. A Cox proportional hazard model from the whole study population to analyze risk factors for severe disease and mortality was calculated. We identified 1052 COVID-19 cases, of which 107 (10.1%) were KTR. In propensity-matched analysis, KTR had higher fever (81.6 % vs. 60%; P = 0.01), lymphopenia (30% vs. 11.7%; P = 0.02), higher neutrophil-to-lymphocyte ratio (43.3% vs. 25%; P = 0.05), and acute kidney injury (66.6% vs. 36.7%; P = 0.001). In Kaplan-Meier survival analysis, there was no difference in mortality or severity of COVID-19. In Cox hazard proportional analysis, the European cooperative oncology group (ECOG) score of 1 to 2 [Hazard ratio (HR) 95% lower confidence interval (CI), upper CI = 4.9 (1.8-13.5); P <0.01], ECOG of >2 [HR = 20 (7.5, 54.7); P <0.01] and waitlisted status [HR = 1.9 (1.1-3.3); P = 0.02] was associated with significant mortality. Kidney transplantation [HR = 0.8 (0.47-1.44); P = 0.5] was not associated with mortality in the analysis. In our report, kidney transplantation status had a different spectrum but was not found to be independently associated with COVID-19 severity or mortality.

Outcomes of Living Donor Kidney Transplant After SARS-CoV-2 Infection in Both the Donor and the Recipient: A Multicenter Study.

OBJECTIVES: Evidence on living donor kidney transplant procedures when both the donor and recipient have had a history of COVID-19 infection is scarce. MATERIALS AND METHODS: We retrospectively explored the protocol, outcomes, and follow-up of 64 donors and recipients of living donor kidney transplant who had recovered from COVID-19. This was a multicenter (n = 12) study from India that included transplants between October 29, 2020, and December 1, 2021. Induction and immunosuppression regimens forthose with different severities of COVID-19 were similar to standard practice. RESULTS: COVID-19 clinical severity ranged from asymptomatic/mild (not requiring oxygen therapy) in 49 recipients (77%) and 63 donors (95.4%) and moderate/severe (requiring oxygen therapy) in 15 recipients (23%) and 1 donor (4.6%). Mean wait time±SEM (SD)from firstdocumentednegative reverse transcriptase-polymerase chain reaction testto surgery for recipients and donors was 90.9 ± 9.27 (74.1) and 47 ± 4.5 (29.2) days, respectively. Six episodes (9.3%) of biopsy-proven acute rejection were reported at follow-up of 214 ± 14.8 (119) days and median of 227 (interquartile range, 109-309) days. The locally weighted scatter plot smoothing curve for creatinine during follow-up in donor-recipients pairs showed no trends of increased creatinine in the context of wait time from COVID-19 to transplant surgery. No graft loss, death, reactivation/reinfection, and complications related to surgery or COVID-19 were reported. CONCLUSIONS: Our report showed excellent outcomes and follow-up data of living donor kidney transplant in recovered donor-recipient pairs with the standard immunosuppression protocol. To our knowledge, this is the first and the largest study of donor-recipient living donor kidney transplant pairs when both donors and recipients had prior COVID-19.

COVID-19 Vaccination in Solid-Organ Transplant: A Real-World Multicenter Experience.

OBJECTIVES: India ranks third globally in organ procurement and transplant and has the second highest COVID-19 incidence rate, but data regarding COVID-19 vaccination in solid-organ transplant patients are scarce. MATERIALS AND METHODS: We created a cross-sectional, anonymous, online questionnaire and sentinvitations to several transplant centers in India. We surveyed vaccine mandates, immunization coverage and side effects, administration timing, infection severity among solid-organ transplant recipients, and booster dosage recommendations. RESULTS: The survey results showedthat vaccinepolicy is heterogeneous among centers; vaccination is voluntary at some centers (44.7%), but some centers have established COVID-19 vaccination as a requirement for transplant candidates (44.6%). CoviShield was the most common vaccine administered (89.3%), and more than 50% of transplant recipients and donors were fully vaccinated. Survey results showed that the pretransplant wait time after full vaccination (both doses) is 2 to 4 weeks (48.9%), and the optimal time for vaccination after transplant is 3 to 6 months (59.3%). For vaccinated transplant patients, 89.4% of respondents reported an incidence rate for posttransplant breakthrough infection of less than 25%. For unvaccinated patients, 38.3% ofrespondents reported a 25% to 50% incidence rate of posttransplant COVID- 19 infection. Booster doses are recommended at many transplant centers in India, as reported by 89.4% of survey respondents. CONCLUSIONS: The results of the survey suggested that there are no substantial safety concerns Future targets should include increasing efficacy and increasing booster doses of the COVID-19 vaccine.

A Narrative Review COVID-19 in Solid-Organ Transplantation: Real-World Evidence From India.

Worldwide, India ranks number 2 and 3 for COVID-19 burden and absolute transplant numbers, respectively. Here, we summarized our single and multicenter Indian studies on solid-organ transplant during the COVID-19 pandemic. During the pandemic, solid-organ transplants declined 40% to 50%. The mortality rate in COVID-19-positive kidney transplant recipients (11.6%) was lower in India compared with the developed world during the first wave and lower compared with maintenance hemodialysis patients (13% to 38%) but significantly higher compared with the nonimmunosuppressed general population (1% to 3%) in India. We contributed to National Organ and Tissue Transplant Organization transplant-related guidelines to increase safety and access to solid-organ transplant. We reported the safety and feasibility of remdesivir (n = 57) and convalescent plasma therapy (n = 10) in kidney transplant recipients. We reported 100% patient and graft survival without any complications related to COVID-19 in a large cohort of kidney transplant recipients who recovered from COVID-19 (n = 372) and a large cohort of kidney transplant recipients of living donors (n = 31) who recovered from COVID-19 without any change in induction and maintenance immunosuppression. COVID-19 disease severity and mortality in the second episode (reoccurring infection) was higher (46%) compared with the first episode (11.6%). There was 4.4% incidence of COVID-19-associated mucormycosis in kidney transplant recipients with mortality of 46% in the second wave. We reported COVID-19 vaccine safety with suboptimal efficacy in kidney transplant recipients and dialysis patients compared with the general population. Our report suggested that transplant with carefully selected COVID-19-recovered donors and patients may be feasible and safe, at least over the short term. Continued research is needed on vaccine efficacy, booster doses, and long-term follow up sequelae.

A Multicenter Cohort Study From India of ABO-Incompatible Kidney Transplantation in Post-COVID-19 Patients.

BACKGROUND: There is a dearth of data regarding the consequences of ABO-incompatible kidney transplant (ABOiKTx) among post-COVID-19 candidates. METHODS: The study was designed as a retrospective, multicentric cohort study across 11 sites in India, from August 2020 to December 2021. The data for ABOiKTx conducted for post-COVID-19 candidates were investigated. The primary outcome of biopsy-proven acute rejection was compared with the ABO protocol implemented through Kaplan-Meier analysis. The secondary outcomes were graft loss, patient survival, and infections. RESULTS: A total of 38 ABOiKTx with candidates of median (interquartile range) age of 38.5 (31.25-47.5) years were performed. Nineteen cases had mild COVID-19 severity, while 9 cases (23.6%) had an oxygen requirement. Six (15.7%) donors also were post-COVID-19. The most common ABO incompatibility reported was A to O in 14 (36.8%) pairs followed by B to O in 10 (26.3%) pairs. The maximum isoagglutinin titer cutoff was 1:2048 and 1:64 for baseline and pretransplant levels, respectively. The median time from COVID-19 infection to surgery was 130 (63.2-183) days. Biopsy-proven acute rejection, graft loss, and mortality were 13.1%, 2.6%, and 2.6%, respectively. The Breslow-Wilcoxon's P value in Kaplan-Meier plots were 0.57 and 0.93 for thymoglobulin-based induction and high dose rituximab-based regimen, respectively. The incidence of reinfection was 2.6%. Two (5.2%) urinary tract infections were reported. No cytomegalovirus or BK polyomavirus infection was reported. The median serum creatinine at 1 year of follow-up was 1.1 (0.8-1.3) mg/dL. CONCLUSIONS: Our report implies that ABOiKTx in post-COVID-19 candidates can be successfully performed with no major deviation from standard ABO protocol.

Humoral and cellular response of COVID-19 vaccine among solid organ transplant recipients: A systematic review and meta-analysis.

BACKGROUND: We aimed to analyze the humoral and cellular response to standard and booster (additional doses) COVID-19 vaccination in solid organ transplantation (SOT) and the risk factors involved for an impaired response. METHODS: We did a systematic review and meta-analysis of studies published up until January 11, 2022, that reported immunogenicity of COVID-19 vaccine among SOT. The study is registered with PROSPERO, number CRD42022300547. RESULTS: Of the 1527 studies, 112 studies, which involved 15391 SOT and 2844 healthy controls, were included. SOT showed a low humoral response (effect size [ES]: 0.44 [0.40-0.48]) in overall and in control studies (log-Odds-ratio [OR]: -4.46 [-8.10 to -2.35]). The humoral response was highest in liver (ES: 0.67 [0.61-0.74]) followed by heart (ES: 0.45 [0.32-0.59]), kidney (ES: 0.40 [0.36-0.45]), kidney-pancreas (ES: 0.33 [0.13-0.53]), and lung (0.27 [0.17-0.37]). The meta-analysis for standard and booster dose (ES: 0.43 [0.39-0.47] vs. 0.51 [0.43-0.54]) showed a marginal increase of 18% efficacy. SOT with prior infection had higher response (ES: 0.94 [0.92-0.96] vs. ES: 0.40 [0.39-0.41]; p-value < .01). The seroresponse with mRNA-12723 mRNA was highest 0.52 (0.40-0.64). Mycophenolic acid (OR: 1.42 [1.21-1.63]) and Belatacept (OR: 1.89 [1.3-2.49]) had highest risk for nonresponse. SOT had a parallelly decreased cellular response (ES: 0.42 [0.32-0.52]) in overall and control studies (OR: -3.12 [-0.4.12 to -2.13]). INTERPRETATION: Overall, SOT develops a suboptimal response compared to the general population. Immunosuppression including mycophenolic acid, belatacept, and tacrolimus is associated with decreased response. Booster doses increase the immune response, but further upgradation in vaccination strategy for SOT is required.

Solid Organ Transplantation in SARS-CoV-2 Recovered Transplant Candidates: a Comprehensive Review of Recent Literature.

Purpose of Review: As the coronavirus disease 2019 (COVID-19) pandemic continues to surge, determining the safety and timing of proceeding with solid organ transplantation (SOT) in transplant candidates who have recovered from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and who are otherwise transplant eligible is an important concern. We reviewed the current status of protocols and the outcomes of SOT in SARS-CoV-2 recovered patients. Recent Findings: We identified 44 published reports up through 7 September 2021, comprising 183 SOT [kidney = 115; lung = 27; liver = 36; heart = 3; simultaneous pancreas-kidney (SPK) = 1, small bowel = 1] transplants in SARS-CoV-2 recovered patients. The majority of these were living donor transplants. A positive SARS-CoV-2 antibody test, although not obligatory in most reports, was a useful tool to strengthen the decision to proceed with transplant. Two consecutive real-time polymerase chain test (RT-PCR) negative tests was one of the main prerequisites for transplant in many reports. However, some reports suggest that life-saving transplantation can proceed in select circumstances without waiting for a negative RT-PCR. In general, the standard immunosuppression regimen was not changed. Summary: In select cases, SOT in COVID-19 recovered patients appears successful in short-term follow-up. Emergency SOT can be performed with active SARS-CoV-2 infection in some cases. In general, continuing standard immunosuppression regimen may be reasonable, except in cases of inadvertent transplantation with active SARS-CoV-2. Available reports are predominantly in kidney transplant recipients, and more data for other organ transplants are needed.

Management strategies and outcomes in renal transplant recipients recovering from COVID-19: A retrospective, multicentre, cohort study.

Background: There is an enormous knowledge gap on management strategies, clinical outcomes, and follow-up after kidney transplantation (KT) in recipients that have recovered from coronavirus disease (COVID-19). Methods: We conducted a multi-center, retrospective analysis in 23 Indian transplant centres between June 26, 2020 to December 1, 2021 on KT recipients who recovered after COVID-19 infections. We analyzed clinical and biopsy-confirmed acute rejection (AR) incidence and used cox-proportional modeling to estimate multivariate-adjusted hazard ratios (HR) for predictors of AR. We also performed competing risk analysis. Additional outcome measures included graft loss, all-cause mortality, waiting time from a positive real-time polymerase test (RT-PCR) to KT, laboratory parameters, and quality of life in follow-up. Findings: Among 372 KT which included 38(10·21%) ABO-incompatible, 12(3·22%) sensitized, 64(17·20%) coexisting donors with COVID-19 history and 20 (5·37%) recipients with residual radiographic abnormalities, the incidence of AR was 34 (9·1%) with 1(0·26%) death censored graft loss, and 4(1·07%) all-cause mortality over a median (interquartile range) follow-up of 241 (106-350) days. In our cox hazard proportional analysis, absence of oxygen requirement during COVID-19 compared to oxygen need [HR = 0·14(0·03-0·59); p-value = 0·0071], and use of thymoglobulin use compared to other induction strategies [HR = 0·17(0·03-0.95); p-value = 0·044] had a lower risk for AR. Degree of Human leukocyte antigen (HLA) DR mismatch had the highest risk of AR [HR = 10.2(1·74-65·83); p-value = 0·011]. With competing risk analysis, with death as a competing event, HLA DR mismatch, and oxygen requirement continued to be associated with AR. Age, gender, obesity, inflammatory markers, dialysis vintage, steroid use, sensitization and ABO-incompatibility have not been associated with a higher risk of AR. The median duration between COVID-19 real time polymerase test negativity to transplant was 88(40-145) days (overall), and ranged from 88(40-137), 65(42-120), 110(49-190), and 127(64-161) days in World Health Organization ordinal scale ≤ 3, 4, 5, and 6-7, respectively. There was no difference in quality of life, tacrolimus levels, blood counts, and mean serum creatinine assessed in patients with a past COVID-19 infection independent of severity. Interpretation: Our findings support that the outcomes of KT after COVID-19 recovery are excellent with absence of COVID-19 sequelae during follow-up. Additionally, there does not seem to be a need for changes in the induction/immunosuppression regimen based on the severity of COVID-19. Funding: Sanofi.

COVID-19 Pandemic Research Opportunities in India: What the Pandemic Is Teaching Us About Transplantation.

Coronavirus disease (COVID-19) has engulfed the whole world, and India has been the second worst-hit nation. Organ transplant services were halted in both the public and private care sectors of India, with public care sectors more adversely affected. Deceased donations were disproportionately more affected, with unfavorable rates at the peak of the pandemic. Mortality outcomes of COVID-19 among different organ transplant recipients in India have been lower compared with the Western world, with younger age and less comorbidities among Indian populations partly responsible for the lower mortality. Mortality and graft loss were mostly associated with older age and those with chronic graft dysfunction. During the pandemic, invasive fungal infections, like mucormycosis, have been reported, illustrating the need for multidisciplinary management. The Indian transplant societies have formulated and timely revised guidelines for transplantation in the COVID-19 era. Living donor transplants (both liver and kidney) after recovery from COVID-19 were both first described in India, providing a guiding tool for the world. Follow-up reports of recovered solid-organ transplant recipients have also been reported in Indian studies, showing reassuring long-term outcomes. Data of breakthrough COVID-19 cases after vaccination among both transplant recipients and waitlist candidates and research in vaccine efficacy for solid-organ transplant recipients is still underway. We suggest continuing and intensifying research activities for a better plan and strategy in case of a future pandemic.

Global Impact of the COVID-19 Pandemic on Solid Organ Transplant.

BACKGROUND: COVID-19 has drastically affected transplant services, but there is limited understanding of the discrepancy of COVID-19 effects on various regions of the world. METHODS: We have explored the Global Observatory for Organ Donation and Transplantation data for assessing the transplant number changes between the calendar year 2019 (n = 157,301) and 2020 (129,681). RESULTS: There was a disproportionate impact of COVID-19 on different areas of the world. Globally, there was a decline of 17.5%, in which deceased donation, kidney (20.9%), pancreas (16.2%), lung (12.7%), liver (11.3%), and heart (8%) transplant declined disproportionally in different regions of the world. The pandemic affected almost all geographic regions and nations, but China and the United States were mostly able to recover from the initial halt of the transplant practices by the pandemic so that there was a cumulative increase in transplant numbers. CONCLUSIONS: Our data show that developing nations lagged behind, whereas developed nations have been able to recover their transplantation programs during the pandemic. Further policy making and preparedness is required to safeguard the most vulnerable areas of the world to minimize the impact of any future pandemic on transplantation practices.

Cytomegalovirus and Severe Acute Respiratory Syndrome Coronavirus 2 Co-infection in Renal Transplants: A Retrospective Study from a Single Center.

There is a scarcity of data regarding the impact of cytomegalovirus (CMV) infection complicating the coronavirus disease-2019 (COVID-19) course. The objective of the study was to explore the clinical profile and outcome of CMV co-infection with COVID-19. This is a single-center retrospective study of COVID-19 cases with concomitant CMV infection. A total of 18 cases were diagnosed with CMV infection during the study period May 2020 to December 2020. The median age (Interquartile range) of the study was 45 (53-38) years with predominant male sex (n = 14, 77%). The baseline donor-recipient status for CMV included D+/R+ (10, 55%), D-/R+(6, 33%), and D+/R- (2, 12%). COVID-19 severity in the study included mild (1, 7%), moderate (5, 28%), severe (8, 44%), and critical (4, 22%) cases. Criteria for hyperinflammatory state was met by 77% (n = 14) of cases. The most common therapeutic modality for COVID-19 given was remdesivir (n = 13), tocilizumab (n = 4), and convalescent plasma (n = 4). The median CMV titer at diagnosis was 1200 (1800-1000) copies/mL. The median duration of hospital stay was 12.5 (14-11). Mortality observed in the study was four (22%). The management of CMV co-infection with COVID-19 is associated with high morbidity and mortality, and we suggest screening for CMV infection in all posttransplant COVID-19 cases.

A Propensity-Matched Analysis of COVID-19 in Kidney Transplant Recipients Compared With Non-Kidney Transplant Patients: A Single-Center Report From India.

OBJECTIVES: Comparisons of COVID-19 incidence between kidney transplant recipients and patients who did not receive kidney transplant are underexplored in various geographic regions. MATERIALS AND METHODS: This Indian, single-center, retrospective study analyzed COVID-19 data of patients hospitalized between May 12, 2020, and January 11, 2021. A propensity matching score was used to compare outcomes between the 2 groups. We also used multivariable Cox proportional hazard analyses to assess association of kidney transplantation with mortality. RESULTS: Of the 1627 COVID-19 cases, 179 were kidney transplant recipients and 1448 were not kidney transplant patients (control group). Ofthe 436 reported in-hospital deaths, 20 (11.1%) were in the kidney transplant group and 416 (28.7%) were in the control group. Propensity matching identified 98 kidney transplantrecipients and167 controlpatients. InKaplanMeier survival plots for these patients, there was no statistical difference in mortality (log-rank, Mantel Cox test; P = .07) or severity (log-rank, Mantel Cox test; P = .07) with regard to COVID-19. In Cox analysis, age groups from 61 to 70 years (hazard ratio = 1.5; 95% CI, 1.0-2.2; P = .04), 71 to 80 years (hazard ratio = 1.64; 95% CI, 1.0-2.5; P = .02), and >80 years (hazard ratio = 1.91; 95% CI, 1.1-3.1; P = .01)were associatedwith statistically significant greater mortality.Having a kidney transplant (hazard ratio = 0.43; 95% CI, 0.3-0.7; P = 0.001) was not associated with mortality. CONCLUSIONS: In our analysis, age was the most important predictor of mortality. Kidney transplant status was not found to have an independent association with mortality and severity.

Impact of COVID-19-associated Mucormycosis in Kidney Transplant Recipients: A Multicenter Cohort Study.

BACKGROUND: COVID-19-associated mucormycosis (CAM) is a recently emerging entity. There is a lack of reports of CAM in organ transplant recipients. METHODS: We conducted a multicenter (n = 18) retrospective research in India during November 2020 to July 2021. The purpose of this study was to explore the clinical spectrum, outcome and risk factors for mortality of CAM in kidney transplant recipients (KTRs). RESULTS: The incidence of CAM was 4.4% (61/1382 COVID-19-positive KTRs) with 26.2% mortality. The median age of the cohort was 45 (38-54) y. Twenty (32%) were not hospitalized and 14 (22.9%) were on room air during COVID-19. The proportion of postdischarge CAM was 59.1%, while concurrent CAM was reported in 40.9%. The presentation of CAM was 91.8% rhino-orbital-cerebral mucormycosis and 8.2% pulmonary with 19.6% and 100% mortality, respectively. In the univariable analysis, older age, obesity, difficulty of breathing, high-flow oxygen requirement, and delay in starting therapy were significantly associated with mortality. In the multivariable logistic regression analysis, patients requiring high-flow oxygen therapy [odds ratio (95% confidence interval) = 9.3 (1.6-51); P = 0.01] and obesity [odds ratio (95% confidence interval) = 5.2 (1-28); P = 0.05] was associated with mortality. The median follow-up of the study was 60 (35-60) d. CONCLUSIONS: We describe the largest case series of CAM in KTRs. Morality in pulmonary CAM is extremely high. Severe COVID-19 pose extra risk for the development of CAM and associated mortality. Our report will help in better understanding the conundrum and management of CAM.

Long-term follow-up of SARS-CoV-2 recovered renal transplant recipients: A single-center experience from India.

INTRODUCTION: Follow-up studies of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in kidney transplant recipients (KTR) are scarcely reported. METHODS: We studied 142 hospitalized KTR for a median (interquartile range) follow-up of 9 (8-11) months who recovered from SARS-CoV-2 during May 2020 to Dec 2020. The outcomes were to assess persistent symptoms post-discharge; EuroQoL visual analogue score (EQ-VAS); EuroQoL 5-dimension score (E5-QD-5L) score and modified medical research dyspnea score (mMRC) at 1 month, 3-month, and beyond 6 months. Graft outcome was also analyzed. RESULTS: The age of the cohort was 43 (34-69) years and COVID-19 severity ranged from asymptomatic (4%), mild (50%), moderate (35%) to severe (12%). The most common persistent symptom was fatigue which significantly decreased in the follow-up (n = 45 [32.3] vs. 10 [7.4] vs. 4 [2.9]; p-value = 0.001) at 1-month, 3-month, and beyond 6 months respectively. Decrement in the mean (standard deviation) EQ-VAS score from baseline was also improved (28.6 [13] vs. 10.4 [12.5] vs. 7.5 [12.0]; p-value = 0.012). There was significant improvement in all EQ-5D-5L scores in follow-up. There was no deterioration in mMRC scores during the follow-up (n = 4, 3% vs. 7, 5% vs. 3, 2%; p-value = 0.86). Cases requiring oxygen had significantly poorer overall scores initially, but there was no difference at 6 months. All 10 graft losses had oxygen requirement and chronic graft dysfunction at baseline. CONCLUSION: Our initial assessment reports significant improvement in the quality of life in follow-up. The majority recovered from allograft dysfunction. Further research is warranted to study the full spectrum of follow-up.

Mucormycosis as SARS-CoV2 sequelae in kidney transplant recipients: a single-center experience from India.

PURPOSE: Coronavirus disease (COVID-19) sequelae in the transplant population are scarcely reported. Post-COVID-19 mucormycosis is one of such sequelae, which is a dreadful and rare entity. The purpose of this report was to study the full spectrum of this dual infection in kidney transplant recipients (KTR). METHODS: We did a comprehensive analysis of 11 mucormycosis cases in KTR who recovered from COVID-19 in IKDRC, Ahmedabad, Gujarat, India during the study period from Nov 2020 to May 2021. We also looked for the risk factors for mucormycosis with a historical cohort of 157 KTR who did not develop mucormycosis. RESULTS: The median age (interquartile range, range) of the cohort was 42 (33.5-50, 26-60) years with 54.5% diabetes. COVID-19 severity ranged from mild (n = 10) to severe cases (n = 1). The duration from COVID-19 recovery to presentation was 7 (7-7, 4-14) days. Ten cases were Rhino-orbital-cerebral-mucormycosis (ROCM) and one had pulmonary mucormycosis. Functional endoscopic sinus surgery (FESS) was performed in all cases of ROCM. The duration of antifungal therapy was 28 (24-30, 21-62) days. The mortality rate reported was 27%. The risk factors for post-transplant mucormycosis were diabetes (18% vs 54.5%; p-value = 0.01), lymphopenia [12 (10-18) vs 20 (12-26) %; p-value = 0.15] and a higher neutrophil-lymphocyte ratio [7 (4.6-8.3) vs 3.85 (3.3-5.8); p-value = 0.5]. CONCLUSION: The morbidity and mortality with post-COVID-19 mucormycosis are high. Post-transplant patients with diabetes are more prone to this dual infection. Preparedness and early identification is the key to improve the outcomes.

Rare and Unusual Follow-up Sequelae of Coronavirus Disease 2019: Splenic Mucormycosis in a Renal Transplant Recipient.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is associated with adverse outcomes in transplantation communities. Mucormycosis, although a rare infection, has been classically linked to organ transplantation and is associated with exceptionally high morbidity and mortality rates. In this pandemic era, the double infection of mucormycosis and COVID-19 is a lethal combination but is rarely described in the literature on organ transplantation. CASE PRESENTATION: This article presents the case of a young kidney transplant recipient with diabetes who acquired severe COVID-19, followed by disseminated mucormycosis. The patient was a health care worker who developed severe COVID-19, for which he received remdesivir, anticoagulation, and dexamethasone. No immunomodulatory therapy was used. His maximum oxygen support was bilevel positive airway pressure ventilation. His sugar levels were frequently deranged during the stay. He developed secondary sepsis with Klebsiella, followed by nonhealing lung consolidation. He later developed pleural effusion and splenic abscess, which was detected incidentally. He underwent an emergency splenectomy, the culture of which yielded mucormycosis. Liposomal amphotericin B 5 mg/kg was administered. The patient deteriorated, and a repeat laparotomy yielded gastric perforation, with pus culture showing mucormycosis. The patient died after a long hospital stay. CONCLUSIONS: The diagnosis and management of this dual infection during the pandemic is extremely challenging. In this case, the unusual location of mucormycosis complicating COVID-19 calls for a meticulous approach to opportunistic fungal infections in organ transplant recipients who are positive for COVID-19, especially in those patients with diabetes.
