Clinical Course and Outcomes of COVID-19 in Kidney Transplant Recipients.

Introduction: Kidney transplant recipients (KTR) are at increased risk of morbidity and mortality due to coronavirus disease 2019 (COVID-19). This study aimed to explore the clinical characteristics and outcomes of COVID-19 in KTR. Methods: We reviewed the clinical profile, outcomes, and immunological responses of recipients admitted with COVID-19. We determined the risk factors for mortality and severe COVID-19. Results: Out of 452 recipients on follow-up, 60 were admitted with COVID-19. Prevalent comorbidities were hypertension (71%), diabetes (40%), lung disease (17%). About 27% had tuberculosis. The median Sequential Organ Failure Assessment score at presentation was 3 (interquartile range [IQR] 1-5). There was a high incidence of diarrhea (52%) and anemia (82%). Treatment strategies included antimetabolite withdrawal (85%), calcineurin inhibitor decrease or withdrawal (64%), increased steroids (53%), hydroxychloroquine (21%), remdesivir (28.3%), and tocilizumab (3.3%). Severe COVID-19 occurred in 34 (56.4%) patients. During a median follow-up of 42.5 days (IQR 21-81 days), 83% developed acute kidney injury (AKI) and eight (13%) died. Mortality was associated with the baseline graft dysfunction, hypoxia at admission, lower hemoglobin and platelets, higher transaminases, higher C reactive protein, diffuse radiological lung involvement, hypotension requiring inotropes, and Kidney Diseases Improving Global Outcomes (KDIGO) stage 3 AKI (univariate analysis). Around 57% of patients remained RT-PCR positive at the time of discharge. By the last follow-up, 66.6% of patients developed IgM (immunoglobulin M) antibodies and 82.3% of patients developed IgG antibodies. Conclusion: COVID-19 in kidney transplant recipients is associated with a high risk of AKI and significant mortality.

Prevalence and subtypes of hypertension in normal-weight and obese Indian adolescents: a cross-sectional study.

This cross-sectional study examined the prevalence, stages, subtypes of hypertension, and the associated risk factors in adolescent school children in Western India. We screened 2,644 adolescents, from 10 different private and government schools in urban and rural areas for hypertension, as defined by the 2017 Clinical Practice Guidelines. The association of stages and subtypes with age, gender, body mass index, type of school, and place of residence was analysed. 197 children (7.5%) had hypertension; 170 (6.4%) had stage I, 27 (1%) had stage II and 76 (2.9%) had elevated blood pressure (EBP). The risk of EBP was higher in children > 15 years of age (p = 0.006). Compared with normal-weight children, obese, and overweight children had a higher risk of hypertension [odds ratio (OR) 9 (5.84, 13.88) and 3.77 (2.59, 5.48) respectively], whereas underweight children had a lower risk [OR 0.39 (0.16, 0.98)]. Normal-weight hypertension was seen in 5.2% and was higher in children from government schools (9.4%). Systolic-diastolic hypertension (SDH) was the most common subtype, seen in 136 (5.1%). SDH was more common in girls, in rural children, and in those with stage II hypertension. Isolated diastolic hypertension, seen in 51 (1.9%), was more common in boys, in urban children, and in those with EBP.

Recovery of kidney function after AKI because of COVID-19 in kidney transplant recipients.

Evidence on the evolution of graft function in kidney transplant recipients recovering from coronavirus disease-2019 (COVID-19) is lacking. This multicenter observational study evaluated the short-term clinical outcomes in recipients with acute kidney injury (AKI) secondary to COVID-19. Out of 452 recipients following up at five centers, 50 had AKI secondary to COVID-19. 42 recipients with at least 3-month follow-up were included. Median follow-up was 5.23 months [IQR 4.09-6.99]. Severe COVID-19 was seen in 21 (50%), and 12 (28.6%) had KDIGO stage 3 AKI. Complete recovery of graft function at 3 months was seen in 17 (40.5%) patients. Worsening of proteinuria was seen in 15 (37.5%) patients, and 4 (9.5%) patients had new onset proteinuria. Graft failure was seen in 6 (14.3%) patients. Kidney biopsy revealed acute tubular injury (9/11 patients), thrombotic microangiopathy (2/11), acute cellular rejection (2/11), and chronic active antibody-mediated rejection (3/11). Patients with incomplete recovery were likely to have lower eGFR and proteinuria at baseline, historical allograft rejection, higher admission SOFA score, orthostatic hypotension, and KDIGO stage 3 AKI. Baseline proteinuria and the presence of orthostatic hypotension independently predicted incomplete graft recovery. This shows that graft recovery may remain incomplete after AKI secondary to COVID-19.

Subcutaneous hyalohyphomycosis caused by Fusarium in a kidney transplant recipient.

Fusarium is a filamentous opportunistic pathogenic fungus responsible for superficial as well as invasive infection in immunocompromized hosts. Net state of immunosuppression and cytomegalovirus (CMV) infection appear to predispose to this disease which is life-threatening when disseminated. Though infections with Fusarium have been widely described in hematological malignancies and hematopoietic stem cell transplant cases, they have been reported to be rare in solid organ transplant recipients, are often localized and carry a favorable prognosis. We here describe a rare case of subcutaneous non-invasive infection with Fusarium in a renal allograft recipient two and half years after transplantation. Patient had a previous history of CMV infection along with multiple other recurrent co-infections. Diagnosis was based on culture of tissue specimens yielding Fusarium species. The infection had a protracted course with persistence of lesions after treatment with voriconazole alone, requiring a combination of complete surgical excision and therapy with the anti-fungal drug.
