Public Health Burden

Globally, SARS-CoV-2 has caused significant public health burden, mainly in patients with underlying comorbidities including both communicable and noncommunicable diseases. Solid organ transplant recipients under immunesupressive medication are also amongst the high risk group. There is only sparse data on immunity against SARS-CoV-2 infection among renal transplant recipients. In this case report, we present the level of anti-SARS-CoV-2 antibody of three kidney transplant recipients after vaccination against COVID-19 virus. All three cases had received two doses of Oxford-AstraZeneca COVID-19 vaccine AZD1222 (ChAdOx1). Serological analysis showed protective level of circulating antibodies in the blood of all three cases. Although two out of three patients in the study acquired COVID-19 infection after immunization, they recovered with mild clinical course. Hence, we conclude that despite immune-suppressed status of transplant recipients, COVID-19 vaccination could protect them against severe illness.

Background. Rituximab is becoming increasingly utilized in renal transplant recipients; however, its association with infections remains unclear. Methods. We reviewed the incidence of viral and fungal infections in kidney transplant recipients treated with () or without () rituximab (RTX) in addition to standard immunosuppression. Results. Infections occurred in 134 (30%) patients, with a greater proportion in RTX versus no RTX patients (47% versus 28%; ). Viral infections occurred in 44% and 27% of RTX and no RTX patients, respectively (). This was largely driven by the frequency of BK viremia and noncytomegalovirus/non-BK viruses in RTX patients (27% versus 13% () and 15% versus 2% (), resp.). Fungal infections also occurred more often in RTX patients (11% versus 3 %; ). Multivariate analysis revealed deceased donor recipient (odds ratio = 2.5; ) and rituximab exposure (odds ratio = 2.2; ) as independent risk factors for infection. Older patients, deceased donor recipients, those on dialysis longer, and those with delayed graft function tended to be at a greater risk for infections following rituximab. Conclusions. Rituximab is associated with an increased incidence of viral and fungal infections in kidney transplantation. Additional preventative measures and/or monitoring infectious complications may be warranted in those receiving rituximab.

Toxoplasma Gondii Infection

Background and Aim: Toxoplasma gondii infection arises in transplant recipient groups, but at varying frequencies. Reactivation of latent T. gondii infection in transplant patients is uncommon, but does occur. The incidence of reactivation is greater in patient groups receiving more aggressive immunosuppressive therapy. Early diagnosis and treatment should be considered in T. gondii-antibody-positive patients subjected to solid organ transplantation. The aim of this study was to estimate the seroprevalence of Toxoplasma gondii infection in renal transplant recipients in Khartoum, Sudan, using serological and molecular methods. Methods: This was a descriptive cross sectional, hospital based study, blood sample were collected from 108 participants; out of them 58 renal transplant recipient individuals and 50 healthy Blood donor attending Sudanese Kidney Association Hospital and Sudan Heart Center Blood Bank. Demographic data were collected by structured questionnaire. All samples were tested for anti-Toxoplasma IgG and IgM antibodies using ELISA, and PCR for detection of Toxoplasma DNA was performed. Results: The seropositivity of IgG anti-T. gondii antibodies was higher in renal transplant recipients than in blood donors (36.2% vs 32.0%). Anti-toxoplasma IgM was positive in one renal transplant recipient individual (1.70%), and no samples exhibit reactive IgM antibody for blood donors. None of the samples exhibited positivity to T.gondii DNA. Conclusion: the study showed a relatively high seroprevalence of T.gondii antibodies in renal transplant recipients and blood donor volunteers, on the other hand, the prevalence was much higher in the study conducted in pregnant woman in Sudan. Our study highlighted that asymptomatic blood donors, may constitute a significant risk of transmitting toxoplasmosis to susceptible recipients.

By April 26, 2020, infections related to coronavirus disease 2019 (COVID-19) affected people from 210 countries and caused 203,818 reported deaths worldwide. A few studies discussed the outcome of COVID-19 in kidney transplant recipients. This short series demonstrates our experience in managing COVID-19 disease in renal transplant patients in the absence of strong evidence. We report 8 cases of kidney transplant recipients infected with COVID-19 (median age = 48.5 years; range = 21–71 years), including 4 males and 4 females. The most frequently associated comorbidity was hypertension. The most common presenting features were fever and cough. The main radiological investigation was a portable chest X-ray. Other common features included lymphopenia, high C-reactive protein, and a very high ferritin level. Overall, 1 patient was managed as an outpatient, the remaining 7 required hospital admission, 1 of them referred to the intensive therapy unit. Management included supportive treatment (intravenous fluid therapy, monitoring renal function, and symptomatic treatment with or without ward-based oxygen therapy depending on oxygen saturation) and discontinuation of the antiproliferative immunosuppressive drugs. Seven patients recovered and discharged home to self-isolate. One patient required intensive care treatment and mechanical ventilation. Supportive treatment could be sufficient for the management or to be tried first. We also found that short hospital stay with self-isolation on discharge reduces the burden on the health service and protect the staff and the public.

ABSTRACT Cryptococcosis is the second most common invasive fungal infection reported in renal transplant recipients. Tissue granulomatous inflammation is necessary to contain Cryptococcus infection. This study aims to analyze the granuloma patterns and in situ expression of regulatory T (Treg) immune response in tissue samples from 12 renal transplant recipients with cryptococcosis. Fungal isolates were molecularly identified as Cryptococcus neoformans species complex. A detailed characterization of granulomas in tissue samples from 12 kidney transplant recipients with cryptococcosis was described by checking six lung and six skin biopsies by conventional histology and for immunohistochemical detection of CD4 and Treg markers: forkhead box P3 (FoxP3), interleukin (IL)-10 and transforming-growth factor (TGF)-β. Granulomas were classified as compact, loose or mixed. Patients with mixed (n = 4) and compact (n = 3) granulomatous inflammation patterns were associated with a better prognosis and presented a higher number of CD4+FoxP3+T cells compared to the group of patients with loose granulomas. In counterpart, three out of five patients with loose granulomas died with cryptococcosis. We suggest that Treg may have a protective role in the tissue response to Cryptococcus infection given its association with compact and mixed granulomas in patients with better clinical outcomes.

Abstract Background and Aims Use of proton-pump inhibitors (PPIs) is common practice in renal transplant recipients (RTRs). Emerging data suggest several adverse effects of use of PPIs, including development of iron deficiency (ID). Although the latter has been shown with respect to PPIs, specific analyses for different types of PPIs and the associated risk of ID have not been performed. Method We used data from the TransplantLines Biobank and Cohort study, an ongoing prospective cohort study among all types of solid organ transplant recipients. For the current study, we used data from stable RTRs with a functional graft for more than 1 year post transplantation (n=795). We excluded RTRs who used any form of iron supplementation (n=54) and EPO-stimulating agents (n=24), resulting in 728 RTRs eligible for analyses. Use of PPIs was subdivided in different types of PPIs, i.e. omeprazole, esomeprazole, pantoprazole, and rabeprazole. ID was defined as TSAT<20% and ferritin <300 µg/L. Logistic regression analysis was used to assess the associations between PPIs and ID. Results We included 728 RTRs (age 56±13 years, 61% males), with a mean eGFR of 53±18 ml/min/1.73m2, a median [interquartile range] ferritin level of 96 (44 – 191) µg/L and mean TSAT of 24±10%. PPIs were used by 504 (69%) of the included RTRs, of which 398 (79%), 55 (11%), 49 (10%), and 2 (0.4%) respectively used omeprazole, pantoprazole, esomeprazole, and rabeprazole. Use of PPIs was strongly associated with ID (OR, 2.20; 95%CI 1.48 – 3.28; P<0.001), independent of adjustment for age, sex, BMI, eGFR, hs-CRP, smoking, alcohol use, use of calcineurine inhibitors, prednisolone, antiplatelet drugs, and antihypertensives. When subdividing the PPIs into the different types, both omeprazole (OR, 1.98; 95%CI 1.39 – 2.83; P<0.001) and esomeprazole (OR, 2.11; 95%CI 1.09 – 4.07; P=0.03) were independently associated with iron deficiency, whereas pantoprazole was not associated (OR, 0.89; 95%CI 0.47 – 1.70; P=0.73). Conclusion Omeprazole and esomeprazole, but not pantoprazole, are associated with an increased risk of ID. Our results are in line with previous reports that pantoprazole has the lowest potency with least increase in intragastric pH, thereby possibly interfering less with reduction of ferric to ferrous iron, and subsequently iron absorption. Future studies are warranted to confirm our present findings.

Risk Of Malignancy

Background.Transplant recipients require immunosuppression to prevent graft rejection. This conveys an increased risk of malignancy, particularly skin tumours. There is a need for up-to-date data for the South of England.Method.Pathology records were reviewed for 709 kidney transplant recipients on immunosuppression at our hospital from 1995 to 2008. Skin tumours were recorded/analysed.Results.Mean age at transplant was 46 years. Mean length of follow-up was 7.2 years and total follow-up was 4926 person-years. 53 (7.5%) patients (39/458 (8.5%) males and 14/251 (5.6%) females) developed ≥1 skin malignancy. Cumulative incidences of 4.0%, 7.5%, and 12.2% were observed for those with <5, <10, and ≥10 years follow-up, respectively. The rate was 45 tumours per 1000 person-years at risk. Additionally, 21 patients (3.0%) only had noninvasive tumours. 221 malignant skin tumours were found: 50.2% were SCCs, 47.1% BCCs, and 2.7% malignant melanomas. Mean years to first tumour were 5.8. Mean number of tumours per patient was 4, with mean interval of 12 months.Conclusions.Despite changes in transplantation practice during the time since the last data were published in this region, these findings are similar to previous studies. This adds to the evidence allowing clinicians to inform patients in this region of their risk.

ABSTRACT This minireview focuses on the microbiologic evaluation of patients with asymptomatic bacteriuria, as well as indications for antibiotic treatment. Asymptomatic bacteriuria is defined as two consecutive voided specimens (preferably within 2 weeks) with the same bacterial species, isolated in quantitative counts of ≥105 CFU/ml in women, including pregnant women; a single voided urine specimen with one bacterial species isolated in a quantitative count ≥105 CFU/ml in men; and a single catheterized urine specimen with one or more bacterial species isolated in a quantitative count of ≥105 CFU/ml in either women or men (or ≥102 CFU/ml of a single bacterial species from a single catheterized urine specimen). Any urine specimen with ≥104 CFU/ml group B Streptococcus is significant for asymptomatic bacteriuria in a pregnant woman. Asymptomatic bacteriuria occurs, irrespective of pyuria, in the absence of signs or symptoms of a urinary tract infection. The two groups with the best evidence of adverse outcomes in the setting of untreated asymptomatic bacteriuria include pregnant women and patients who undergo urologic procedures with risk of mucosal injury. Screening and treatment of asymptomatic bacteriuria is not recommended in the following patient populations: pediatric patients, healthy nonpregnant women, older patients in the inpatient or outpatient setting, diabetic patients, patients with an indwelling urethral catheter, patients with impaired voiding following spinal cord injury, patients undergoing nonurologic surgeries, and nonrenal solid-organ transplant recipients. Renal transplant recipients beyond 1 month posttransplant should not undergo screening and treatment for asymptomatic bacteriuria. There is insufficient evidence to recommend for or against screening of renal transplant recipients within 1 month, patients with high-risk neutropenia, or patients with indwelling catheters at the time of catheter removal. Unwarranted antibiotics place patients at increased risk of adverse effects (including Clostridioides difficile diarrhea) and contribute to antibiotic resistance. Methods to reduce unnecessary screening for and treatment of asymptomatic bacteriuria aid in antibiotic stewardship.

Human metapneumovirus (hMPV) is emerging as a cause of a severe respiratory tract infection in immunocompromised patients. hMPVpneumonia has only been seldom reported in nonpulmonary solid organ transplanted patients, such as renal transplant recipients. We report here a case of a 39-year-old patient presenting with fever, cough, and interstitial opacities on CT scan diagnosed as a nonsevere hMPVpneumonia 11 years after a renal transplantation. Infection resolved spontaneously. Differential diagnosis withPneumocystispneumonia was discussed. We review the medical literature and discuss clinical presentation and detection methods that can be proposed in solid organ transplant recipients.
