Immunization with influenza vaccine remains an important global health strategy to prevent outbreaks and epidemics of seasonal influenza. Influenza vaccine has rarely been associated with vasculitis, acute kidney injury (AKI) and nephrotic syndrome (NS). Glomerular diseases following influenza vaccination have also been rarely reported. We report a patient who developed acute-onset massive proteinuria with NS and severe AKI soon after receiving the 2009 H1N1 influenza vaccine. Kidney biopsy showed membranous nephropathy (MN) and acute interstitial nephritis (AIN). Optimal management of glomerular diseases or AIN following influenza vaccination is not known. Our patient responded well to an initial course of oral corticosteroid therapy with normalization of serum creatinine level but had a relapse of NS with AKI soon after completion of corticosteroid therapy. A repeat kidney biopsy revealed MN and resolved AIN. A subsequent prolonged course of oral corticosteroids resulted in complete clinical remission of the NS as well as normalization of renal function. Long-term response to corticosteroid therapy in such cases is not known. However, our patient continued to remain in clinical remission with normal renal function, five years after the initial treatment.

Acute renal failure (ARF) requiring hemodialysis is not common among patients affected by influenza. We report two unvaccinated adult patients with smoking habit, which were admitted with severe influenza A H1N1pdm09 that evolved with shock and required mechanical ventilation. Both patients developed progressive renal failure with oliguria/anuria, associated with urinary of inflammatory sediment with proteinuria, microhematuria and in one case also with hypocomplementemia, suggesting acute glomerulonephritis. Renal replacement therapy (RRT) was required in both cases. In one patient, who died of late complications, sequencing of the HA1 segment revealed the previously described D222N mutation associated to severe cases. ARF with RRT appears to be an uncommon complication of patients hospitalized for influenza A H1N1pdm09 and may be secondary to acute glomerulonephritis.

We present the case of a 75-year-old Hispanic woman with known stage 3 chronic kidney disease, long-standing hypertension and type 2 diabetes mellitus who presented with right-sided abdominal pain and acute kidney injury, nephrotic range proteinuria with positive antimyeloperoxidase antibody. A renal biopsy revealed IgA nephropathy with superimposed pauci-immune antineutrophilic cytoplasmic antibody (ANCA)-associated crescentic glomerulonephritis. The patient was treated with pulse intravenous methylprednisolone, cyclophosphamide and plasmapheresis. One week after her second dose of cyclophosphamide, she was readmitted for infectious complications including influenza A respiratory infection, Rothia bacteraemia associated with diarrhoea and herpes zoster of the trunk. In this report, we review the prevalence, treatment and prognosis of coexistent IgA nephropathy and pauci-immune ANCA-associated crescentic glomerulonephritis. We propose that a reduced-dose treatment regimen should be considered in elderly patients due to their higher risk of infectious complications. Current literature suggests that this treatment approach may reduce infectious complications without compromising therapeutic efficacy.

Leontopodium leontopodioides (Willd.) Beauv. is used therapeutically to prevent numerous diseases. Historically, L. leontopodioides extracts have been used to treat influenza infections, bronchitis, acute and chronic nephritis, proteinuria, hematuria, and diabetes. However, the bioactive compounds that are responsible for the associated therapeutic effects have not yet been characterized. In this study, high-performance liquid chromatography was utilized to study the anti-inflammatory properties of L. leontopodioides through analysis of spectrum-effect relationships. The bioactive compounds that correlated with anti-inflammatory activities were partially identified. Following aqueous extraction, a variety of different polar organic solvents including petrol ether extracts, ethyl acetate extracts, n-butanol extracts, and residual aqueous extracts were successfully isolated from L. leontopodioides. These extracts were analyzed using high-performance liquid chromatography to generate HPLC fingerprints. A total of 32 common peaks were selected following a similarity analysis (SA). The spectrum-effect relationship was subsequently studied and inflammatory factors were identified following acute inflammatory experiments. The results revealed that the main peaks associated with anti-inflammatory activities were x1, x3, x4, x13, x14, x16 for interleukin-1 (IL-1), x5, x8, x9, x18, x26, x27, x30, x31, x32 for interleukin-6 (IL-6), and x28 and x29 for leukotriene B4 (LTB4). Following analysis of HPLC data, peaks x9 and x14 were identified as chlorogenic acid and ferulic acid, respectively. The current study utilized HPLC and pharmacological analyses to formulate a spectrum-effect relationship and identify bioactive compounds in L. leontopodioides.

Puumala orthohantavirus (PUUV) is the most prevalent of the four species of zoonotic hantaviruses found in Europe, causing nephropathia epidemica, a mild form of hemorrhagic fever with acute kidney injury that presents with elevated serum creatinine level, proteinuria and hematuria. The febrile phase of the infection begins with flu-like syndrome and visual disturbance. Laboratory results can show thrombocytopenia. The oliguric phase with elevated serum creatinine level then occurs. Cardiac involvement is sometimes observed, especially ECG abnormality: transient T-waves inversion, generally in the lateral or inferior leads. Marked bradycardia has been exceptionally described. We report the case of a 36-year-old woman with acute PUUV infection. Two days after admission, the patient presented a sinus bradycardia at 25/min. The bradycardia was asymptomatic, persisted one week and resolved spontaneously. Cardiac involvement in Puumala virus infection seems not to be associated with a bad prognosis. Bradycardia in the course of an influenza-like illness in endemic areas should suggest several pathogens such as legionella, Q fever or PUUV virus infection.

Tubulointerstitial nephritis and uveitis (TINU) syndrome is a rare disease characterised by the association of acutetubulointerstitial nephritis and uveitis. It affects mainly children and young women. Drugs and infections may be precipitating factors. It is a diagnosis of exclusion. The mainstays of treatment are topical and systemic corticosteroids. Prognosis is usually favourable. We report a case of TINU which occurred in our unit. A 37-year-old woman presented with an influenza-like illness, bilateral ocular pain and blurred vision. Ophthalmological evaluation revealed bilateral anterior uveitis and later renal involvement was seen as acute tubulointerstitial nephritis. A diagnosis of TINU was assumed after exclusion of other systemic diseases. She was treated with topical corticosteroids for the uveitis and evolved favourably, with resolution of ocular symptoms and normalisation of serum creatinine and proteinuria. This case highlights the importance of a high degree of clinical suspicion to make the diagnosis of TINU syndrome.
