Background: Acute kidney injury (AKI) is one of the major determinants of graft survival in kidney transplantation (KTx). Renal Transplant recipients are more vulnerable to develop AKI than general population. AKI in the transplant recipient differs from community acquired, in terms of risk factors, etiology and outcome. Our aim was to study the incidence, risk factors, etiology, outcome and the impact of AKI on graft survival. Methods: A retrospective analysis of 219 renal transplant recipients (both live and deceased donor) was done. Results: AKI was observed in 112 (51.14%) recipients, with mean age of 41.5 ± 11.2 years during follow-up of 43.2 ± 12.5 months. Etiologies of AKI were infection (47.32%), rejection (26.78%), calcineurin inhibitor (CNI) toxicity (13.39%), and recurrence of native kidney disease (NKD) (4.46%). New Onset Diabetes After Transplant (NODAT) and deceased donor transplant were the significant risk factors for AKI. During follow-up 70.53% (p = .004) of AKI recipients progressed to chronic kidney disease (CKD) in contrast to only 11.21% (p = .342) of non AKI recipients. Risk factors for CKD were AKI within first year of transplant (HR: 7.32, 95%CI: 4.37–15.32, p = .007), multiple episodes of AKI (HR: 6.92, 95%CI: 3.92–9.63, p = .008), infection (HR: 3.62, 95%CI: 2.8–5.75, p = .03) and rejection (HR: 9.92 95%CI: 5.56–12.36, p = .001). Conclusion: Renal transplant recipients have high risk for AKI and it hampers long-term graft survival.

Systemic lupus erythematosus (SLE) and myasthenia gravis (MG) are two autoimmune diseases that have a higher incidence in young females, relapsing–remitting course, and positive antinuclear antibodies. SLE and MG are two different clinical syndromes, which can coexist or precede each other; however, their occurrence in the same patient is rare. We report a 38-year-old female with biopsy-proven lupus nephritis on steroids and cyclophosphamide, later developed MG. Nerve conduction studies showed the decremental response of 15%–25% over facial muscles with no decremental response over limb muscles. Although antianticholinesterase receptor (AchR) antibodies were negative, she was treated with oral pyridostigmine 60 mg twice daily and clinical improvement of ocular symptoms was seen within 48 h. At present, she is on oral prednisolone and mycophenolate mofetil with follow-up creatinine of 1.4 mg/dl and no neurological symptoms.

IgA-dominant infection-related glomerulonephritis (IRGN) is a distinct morphologic variant of IRGN, characterized by dominant or codominant glomerular deposits of IgA, mostly in elderly and patients with diabetes. More cases are being reported in recent times due to increased awareness of the disease entity and increased rate of Staphylococcus infection. It usually presents as rapidly progressive renal failure with proteinuria, and treatment guidelines for this disease entity are not well defined. We report here 12 cases of IgA-dominant IRGN seen over a period of 5 years from a single center. Clinical features, biopsy findings, treatment, and outcomes were analyzed. Out of 12 patients, eight were males. The mean age of presentation was 52.4 ± 21 years. Skin was the most common site of infection seen in six patients. Gross hematuria was seen in 4 patients and 11 had nephrotic proteinuria. Eleven had low serum C3. Only two patients had diabetes. Methicillin-resistant Staphylococcus aureus (MRSA) was the most common organism isolated in six patients. Most common histopathology was crescentic glomerulonephritis seen in seven patients, followed by endocapillary proliferation in three and diffuse proliferative glomerulonephritis in two. Hemodialysis was done in eight patients and six patients received steroid therapy. End-stage renal disease developed in three patients, chronic kidney disease in three, and three patients died due to sepsis. Various infections including MRSA and Escherichia coli were associated with IgA-dominant IRGN both in patients with diabetes and nondiabetics. Suspicion and recognition of the disease is important as it has therapeutic and prognostic implications.
