Wide Usage

Rituximab is a chimeric anti-CD20 monoclonal antibody that has been widely used to treat CD 20 positive hematologic malignancies and some autoimmune conditions. Although usually well tolerated, an increasing number of serious complications related to rituximab have been noted with its wide usage. We report a 67-year-old man who developed biopsy-proven Allergic Interstitial Nephritis (AIN) after treatment with rituximab for his Primary Central Nervous System Lymphoma (PCNSL). Rituximab-induced AIN was confirmed by kidney biopsy, and his kidney function improved to his baseline with supportive care and four weeks of steroid treatment. While rare, AIN could be a possible adverse effect of rituximab. To our knowledge, this is the first case report of a biopsy-proven AIN from rituximab. The association of AIN and rituximab in our case necessitates a high index of suspicion to facilitate early detection of AIN and timely discontinuation of the offending medication.

Systemic Manifestations

Drug-induced lupus erythematosus has features distinct from primary systemic lupus erythematosus. It can occur with a wide variety of agents that result in the generation of anti-histone or other types of antibodies. Systemic manifestations of drug-induced systemic lupus erythematosus may include renal dysfunction due to circulating immune complexes or due to other immune reactions to the culprit medication(s). Acute interstitial nephritis occurs due to DNA–drug or protein–drug complexes that trigger an allergic immune response. We report a patient who developed acute kidney injury, rash, and drug-induced systemic lupus diagnosed by serologies after starting chlorthalidone and amiodarone. A renal biopsy showed acute interstitial nephritis and not lupus-induced glomerulonephritis. It is important to note that systemic lupus erythematosus and acute interstitial nephritis can occur together, and this report highlights the role of the kidney biopsy in ascertaining the pathological diagnosis and outlining therapy in drug-induced lupus erythematosus.

Abstract Background Acute kidney injury (AKI) associated with severe coronavirus disease 19 (COVID-19) is common and is a significant predictor of morbidity and mortality, especially when dialysis is required. Case reports and autopsy series have revealed that most patients with COVID-19 – associated acute kidney injury have evidence of acute tubular injury and necrosis - not unexpected in critically ill patients. Others have been found to have collapsing glomerulopathy, thrombotic microangiopathy and diverse underlying kidney diseases. A primary kidney pathology related to COVID-19 has not yet emerged. Thus far direct infection of the kidney, or its impact on clinical disease remains controversial. The management of AKI is currently supportive. Case Presentation The patient presented here was positive for SARS-CoV-2, had severe acute respiratory distress syndrome and multi-organ failure. Within days of admission to the intensive care unit he developed oliguric acute kidney failure requiring dialysis. Acute kidney injury developed in the setting of hemodynamic instability, sepsis and a maculopapular rash. Over the ensuing days the patient also developed transfusion-requiring severe hemolysis which was Coombs negative. Schistocytes were present on the peripheral smear. Given the broad differential diagnoses for acute kidney injury, a kidney biopsy was performed and revealed granulomatous tubulo-interstitial nephritis with some acute tubular injury. Based on the biopsy findings, a decision was taken to adjust medications and initiate corticosteroids for presumed medication-induced interstitial nephritis, hemolysis and maculo-papular rash. The kidney function and hemolysis improved over the subsequent days and the patient was discharged to a rehabilitation facility, no-longer required dialysis. Conclusions Acute kidney injury in patients with severe COVID-19 may have multiple causes. We present the first case of granulomatous interstitial nephritis in a patient with COVID-19. Drug-reactions may be more frequent than currently recognized in COVID-19 and are potentially reversible. The kidney biopsy findings in this case led to a change in therapy, which was associated with subsequent patient improvement. Kidney biopsy may therefore have significant value in pulling together a clinical diagnosis, and may impact outcome if a treatable cause is identified.

Rare Diagnosis

Granulomatous interstitial nephritis (GIN) is a rare entity identified in <1% of native kidney biopsies. The most frequent aetiology is drug-related, followed by systemic granulomatous conditions. Among drugs implicated in GIN, antibiotics and non-steroidal anti-inflammatory drugs (NSAIDs) are the most frequent. We report the case of a 45-year-old white man referred to a nephrology consult due to chronic kidney disease. He had a history of arterial hypertension with 10 years of evolution, hyperuricaemia, medicated with allopurinol and NSAID abuse for at least 20 years. Urine sediment was blunt, without proteinuria. Renal ultrasound was normal. A kidney biopsy revealed well-defined epithelioid granulomas with glomerular wrinkling and collapse. Infectious and systemic conditions were excluded, favouring the hypothesis of drug-induced GIN, probably related to NSAIDs. Kidney biopsy remains the gold standard for the diagnosis of GIN. Facing a patient with renal failure without significant proteinuria or active sediment, one should look for causes of tubulointerstitial injury.

Among the causes of acute interstitial nephritis, drug-induced acute interstitial nephritis accounts for 50 to 78 % of all cases. Th e review summarizes the literature data on drugs that cause acute interstitial nephritis. Search in eLibrary databases.RU, PubMed®, MEDLINE, EMBASE, manuals and guidelines, materials of adverse drug reactions databases, instructions for the medical use of drugs. it was held until October 2020. Th e most probable mechanisms of its development are considered. Most attention is paid to non-steroidal anti-infl ammatory drugs, anticoagulants, antibiotics, antitumor drugs (immune checkpoint inhibitors), which are widely used in clinical practice. Th e symptoms of drug-induced acute interstitial nephritis are variable and oft en non-specific; therefore, a kidney biopsy is required for an accurate diagnosis. The main direction of treatment of drug-induced acute interstitial nephritis is the cancellation of nephrotoxic drugs, if this condition is not feasible and/or the duration of acute interstitial nephritis is less than 3 weeks, the biopsy has minimal interstitial fibrosis and there are no serious contraindications, then the possibility of using it should be considered.

Background:Multiple xanthogranulomas (XGs) in adults are rare, although an increasing number of case reports are being published. The most frequent association is hematologic malignancies, but the majority of cases remain idiopathic, with occasional spontaneous resolution.Objective:The aims of this report are to describe a case of eruptive XG in a woman with a solid neoplasia who was receiving imatinib and to review the literature.Methods and Results:This 33-year-old woman had a gastrointestinal stromal tumor. After undergoing surgical removal and being on imatinib for 1 year, the patient developed multiple slightly erythematous papules with an orange hue on the axillary region, trunk, abdomen, and thighs. A biopsy confirmed the diagnosis of XG.Conclusion:This is to the investigators’ knowledge the first case of eruptive XG in the setting of a solid neoplasia. The possibility of drug-induced XG lesions due to imatinib cannot be excluded. This presentation could be added to the list of associations of adult XG.

Background. Acute interstitial nephritis (AIN) is a frequent cause of Acute Kidney Injury (AKI). Drug hypersensitivity is the most common etiology and the list of drugs that can induce AIN is not exhaustive yet.Case Report. Here, we describe the case of a 43-year-old man who was treated with nifedipine (Adalate®) for Raynaud’s syndrome. After nifedipine introduction, serum creatininemia progressively increased from 91 to 188 μmol/L in a few months and AKI was diagnosed. Laboratory work-up results indicated the presence of tubular proteinuria and nonspecific inflammatory syndrome. Histological analysis found granulomatous interstitial nephropathy without necrosis in 20% of the kidney biopsy without immunofluorescent deposit. Nifedipine was stopped and corticosteroid treatment was started with a rapid but incomplete reduction of serum creatininemia level to 106 μmol/L.Conclusion. This is the first case of AIN caused by nifedipine.

Background: The cytotoxic T-lymphocyte antigen-4 (CTLA-4) pathway acts as a negative immune regulator of T-cell activation and promotes self-tolerance. Case: We report the first case of biopsy-proven central nervous system inflammatory demyelination in the context of primary immunodeficiency and a novel CTLA-4 variant. Conclusion: This case has significant implications for the development of novel treatments for autoimmune conditions including multiple sclerosis and further emphasises the need for caution with clinical use of CTLA-4 immune checkpoint inhibitors in those with a history of inflammatory demyelination.

Abstract Background Sodium-glucose co-transporter 2 (SGLT2) inhibitors are novel hypoglycemic agents which reduce reabsorption of glucose at the renal proximal tubule, resulting in significant glycosuria and increased risk of genital mycotic infections (GMI). These infections are typically not severe as reported in large systematic reviews and meta-analyses of the medications. These reviews have also demonstrated significant cardiovascular benefits through other mechanisms of action, making them attractive options for the management of Type 2 diabetes mellitus (T2DM). We present two cases with underlying abnormalities of the urogenital tract in which the GMI were complicated and necessitated cessation of the SGLT2 inhibitor. Case presentations Both cases are patients with T2DM on empagliflozin, an SGLT2 inhibitor. The first case is a 64 year old man with Candida albicans balanitis and candidemia who was found to have an obstructing renal calculus and prostatic abscess requiring operative management. The second case describes a 72 year old man with Candida glabrata candidemia who was found to have prostatomegaly, balanitis xerotica obliterans with significant urethral stricture and bladder diverticulae. His treatment was more complex due to fluconazole resistance and concerns about urinary tract penetration of other antifungals. Both patients recovered following prolonged courses of antifungal therapy and in both cases the SGLT2 inhibitor was ceased. Conclusions Despite their cardiovascular benefits, SGLT2 inhibitors can be associated with complicated fungal infections including candidemia and patients with anatomical abnormalities of the urogenital tract may be more susceptible to these infections as demonstrated in these cases. Clinicians should be aware of their mechanism of action and associated risk of infection and prior to prescription, assessment of urogenital anatomical abnormalities should be performed to identify patients who may be at risk of complicated infection.
