Nocardiosis in Renal Transplantation: Case Series from India.

Nocardiosis is a rare opportunistic infection seen in kidney transplant patients and is caused by aerobic actinomycete. Disease manifestations can vary from a localized infection to multisystem organ failure. In this retrospective case series, we present 16 cases of Nocardiosis. The median age of the patients was 44 years. The median time from transplant to nocardiosis was 21 months. Acute rejection episodes and CMV infection within 6 months of nocardiosis were found in 12.5% and 25%, respectively. The most common organ involvement was the lungs (75%), followed by the brain (12.5%). Only one patient showed cutaneous involvement (6.25%). Mean creatinine at presentation was 0.7 mg/dL (mean eGFR: 92 ± 27 mL/min/1.73 m2). Trimethoprim/sulfamethoxazole resistance was found in 25% of patients. Five patients (31.25%) succumbed to the infection. Nocardiosis has a very low incidence but a high rate of mortality.

Role of colour Doppler in predicting foetal outcome in maternal anaemia.

Context: Anaemia is the most common nutritional deficiency in Indian pregnant females. It ensues foetal hypoxia resulting in different compensatory mechanisms in the foetus which may result in adverse perinatal outcomes. Colour Doppler can be used to measure these hemodynamic changes of the foetus ahead of the clinical manifestations, guiding the obstetrician for the appropriate management and circumventing any dire complication. Aims: The aim of this study is to detect foetal haemodynamic changes associated with maternal anaemia and assess the parameters which predict these changes accurately. Settings and Design: Prospective cohort study. Materials and Methods: Two hundred and forty pregnant females in the third trimester, divided into four groups based on their haemoglobin levels in the non-anaemic, mild, moderate and severe anaemic groups, were included in the study. These patients were followed up for foetal outcome in terms of effective foetal weight, APGAR score and neonatal intensive care unit admission. Statistical Analysis Used: Analysis of Variance Appearance, Pulse, Grimace, Activity and Respiration (ANOVA) test was used to compare the quantitative variables. SPSS software was used. Results: The middle cerebral artery (MCA) Doppler indices and cerebroplacental ratio (CPR) values were increasing while umbilical Doppler indices were decreasing with the increasing severity of anaemia. CPR was found to be the most sensitive predictor for foetal outcome. Conclusions: Maternal anaemia results in foetal hypoxia which can be measured in terms of foetal Doppler indices. CPR was found to be more sensitive than the umbilical or MCA in predicting foetal hypoxia and in turn the perinatal outcome of foetuses of anaemic pregnant females. The foetuses with low CPR values will require urgent intervention to improve the outcomes.

Atypical HUS Triggered by COVID-19: A Case Report.

We hereby present a case of an atypical hemolytic uremic syndrome (aHUS) precipitated by coronavirus disease 2019 (COVID-19). A 26-year-old male was diagnosed with COVID-19 and acute kidney injury. His kidney biopsy was suggestive of thrombotic microangiopathy. Five sessions of plasmapheresis were done but were discontinued in view of nonrecovery of kidney function. He was then referred for a kidney transplant. On genetic analysis, he was found to have mutations in the complement system (CFHR1 and CFHR3), which suggested this was a case of aHUS precipitated by COVID-19. In view of the high risk of recurrence of the primary disease in live-related kidney donor transplantation, he was advised for simultaneous liver and kidney transplants.

Short- and long-term outcomes of early initiation of peritoneal dialysis following catheter insertion.

INTRODUCTION: Early-start peritoneal dialysis (PD) (use of PD catheter within 48 hours of insertion) is an innovative approach for prompt initiation of PD. AIM: This study was conducted to analyze the outcomes of early-start PD. MATERIALS AND METHODS: A total of 100 patients on PD were retrospectively analyzed. Patients were grouped according to the "break-in period": < 48 hours (PD1) and ≥ 14 days (PD2). PD was initiated with low dwell volumes (500 mL) in a recumbent position within 48 hours of surgery. PD prescription was gradually incremented over 10 days to minimize any complications. RESULTS: In our study, there were 48 patients in the PD1 group and 52 in the PD2 group. The most common cause of end-stage kidney disease (ESKD) was diabetes mellitus in both groups. Incidence of early mechanical complications (within 30 days of catheter insertion), such as catheter obstruction, early catheter leakage, catheter malposition, tip migration, and infectious complications, were not found to be higher in the PD1 group. 1- and 4-year catheter patency rates were 97.0% and 96.2% in the PD1 group, respectively. These rates were comparable with those in the PD2 group. Early-start PD was not associated with an increased incidence of catheter failure (HR = 1.0, 95% CI 0.28 - 3.47). CONCLUSION: An early break-in period of < 48 hours is a feasible option for ESKD patients without any significantly increased risk of mechanical or infectious complications. It offers a safe and efficacious option for renal replacement therapy.

Double whammy: anticoagulant-related nephropathy with leukocytoclastic vasculitis due to warfarin.

Anticoagulation-related nephropathy (ARN) is a rare form of acute kidney injury where the use of anticoagulation causes hemorrhage in various compartments of nephron including glomerulus, renal tubules, and interstitial compartment. Also, warfarin-induced vasculitis is an extremely rare condition characterized by the appearance of purpuric lesions on the skin which on biopsy are suggestive of leukocytoclastic vasculitis (LV). We hereby report a case presenting with coexistent warfarin-induced nephropathy and cutaneous vasculitis. A 64-year-old male, on warfarin for 10 years, presented with complaints of palpable purpuric rashes over lower limbs, hematuria, and decrease urine output. INR was in the supratherapeutic range (INR-6.3). Skin biopsy of the lesion was suggestive of LV and kidney biopsy showed RBCs in Bowman's capsule, RBCs and RBC casts in tubules suggestive of ARN. All vasculitic markers were negative. Thus, a diagnosis of warfarin-induced nephropathy and cutaneous vasculitis was made. Warfarin was discontinued and oral steroids were started. Gradually, his skin lesions improved, and he became dialysis independent. He was then discharged on apixaban. On follow-up after 3 months, his skin lesions had disappeared with partial recovery of kidney function (cr-5.49).

IgA Nephropathy with Wilson's Disease: A Case Report and Literature Review.

The most common glomerulonephritis seen in the world is immunoglobulin A nephropathy (IgAN). It can be primary or secondary associated with various conditions like Chronic Liver disease, Crohn's disease, neoplasms, etc. However, IgAN secondary to Wilson's disease is very rare. A 9 year old boy presented with gross hematuria and proteinuria. He had a history of recurrent jaundice in the past. Ultrasonography (USG) whole abdomen showed altered echotexture of the liver with normal-sized kidneys. An extended workup for liver disease was done, and the diagnosis of Wilson's disease was confirmed with decreased serum ceruloplasmin levels, increased urinary copper, and the Kayser-Fleischer ring. Urine routine microscopy showed numerous red blood cells, few red blood cell casts, and mild proteinuria. Renal biopsy showed IgAN. The patient was started on D-penicillamine. On follow-up at 3 months, he showed complete resolution of proteinuria and hematuria. Thus, we suggest that Wilson's disease should be considered as one of the causes of secondary IgAN in pediatric patients with hematuria, proteinuria with liver dysfunction.

Chylous Ascites after Laparoscopic Donor Nephrectomy: Case Report.

Chylous ascites refers to the accumulation of chyle in the abdominal cavity. Postoperative chylous ascites is most commonly associated with abdominal aortic surgeries. However, it is a rare complication following laparoscopic nephrectomy. It causes loss of fat, protein, and antibodies causing malnutrition and immunodeficiency. Thus, it is important to treat it as early as possible. We hereby report a case of chylous ascites following laparoscopic donor nephrectomy. A 55-year-old female was admitted at our center 2 weeks after undergoing left laparoscopic donor nephrectomy with abdominal distension and constipation. USG abdomen revealed free fluid in the abdomen. Paracentesis revealed chylous ascites. The patient was started on conservative treatment, including a diet rich in proteins and low in fats; conservative treatment, however, was unsuccessful. Lymphangiography and subsequent embolization of the defect were done, and she made a full recovery.

COVID-19 Infection in Renal Transplant Patients: Early Report From India.

INTRODUCTION: COVID -19 has gripped the whole world and patients with comorbidities especially kidney ailments are at higher risk of developing severe disease. Among kidney disease, transplant patients are the most vulnerable group. Information on coronavirus disease 2019 (COVID-19) in kidney transplant patients is very limited. METHODS: An observational study was conducted on 20 kidney transplant patients who tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by polymerase chain reaction from April to June 2020. RESULTS: The majority of cases were males (85%). The median age of the patients was 50 years (interquartile range [IQR] 40.75-60.75). Diabetes and hypertension were present in 55% and 95% of patients, respectively. Coronary artery disease was present in three patients (15%). The median time from transplant to COVID-19 testing was 54 months (IQR 36-105). Chronic allograft nephropathy was found in 35% of patients. The mean baseline creatinine was 1.71 mg/dL. The most common symptom was fever (80%). Acute Kidney Injury was seen in 60% of patients with a mean creatinine of 2.60 mg/dL. Based on severity, 50% of patients had mild disease, 25% moderate disease, and the remaining 25% had severe disease. All 20 patients were on oral steroids, calcineurin inhibitors (18 on tacrolimus and two on cyclosporine), and antimetabolite (19 on mycophenolate mofetil and one on azathioprine). Antimetabolite agents were stopped in all patients and tacrolimus was stopped in severe cases (25%). Hydroxychloroquine was given in 15 patients (75%). Fifteen patients (75%) recovered while five (25%) died. CONCLUSION: Kidney transplant recipients infected with COVID-19 have high mortality.

CMV presenting as a skin growth in renal transplant patient.

CMV infection is one of the most common opportunistic infection in kidney transplant patients. If not treated, it is associated with increased mortality and graft loss. It can present as viremia or CMV disease in the form of CMV syndrome or tissue invasive CMV disease. The cutaneous presentation of CMV disease is a rare finding. Its identification is vital as cutaneous CMV infection can signal systemic infection and poor prognosis. In our case, 46-year-old male who was a post renal allograft recipient (RAR) presented as a protuberant growth over the medial side of the left ankle. On skin biopsy, nucleomegaly and inclusion bodies were seen in the epithelial cells. Immunohistochemistry was positive for CMV infection. Patient was treated with Ganciclovir, however, he succumbed to death because of severe sepsis due to secondary bacterial infection. Thus, CMV disease should always be kept in mind in immunocompromised patients like post RAR patients who present with cutaneous features like ulcerative lesions or fungating growth.
