The interaction of reactive oxygen species (ROS) with lipids, proteins, nucleic acids and hydrocarbonates promotes acute and chronic tissue damage, mediates immunomodulation and triggers autoimmunity in systemic lupus erythematous (SLE) patients. The aim of the study was to determine the pathophysiological mechanisms of the oxidative stress-related damage and molecular mechanisms to counteract oxidative stimuli in lupus nephritis. Our study included 38 SLE patients with lupus nephritis (LN group), 44 SLE patients without renal impairment (non-LN group) and 40 healthy volunteers as control group. In the present paper, we evaluated serum lipid peroxidation, DNA oxidation, oxidized proteins, carbohydrate oxidation, and endogenous protective systems. We detected defective DNA repair mechanisms via 8-oxoguanine-DNA-glycosylase (OGG1), the reduced regulatory effect of soluble receptor for advanced glycation end products (sRAGE) in the activation of AGE-RAGE axis, low levels of thiols, disulphide bonds formation and high nitrotyrosination in lupus nephritis. All these data help us to identify more molecular mechanisms to counteract oxidative stress in LN that could permit a more precise assessment of disease prognosis, as well as developing new therapeutic targets.

Membranoproliferative glomerulonephritis (MPGN) has previously been used as an umbrella term to describe a spectrum of hypocomplementemic glomerular diseases, which are rare causes of end stage kidney disease (ESKD). We present a 22-year-old man with a well-established medical history who had been complaining of 4 days of frothy dark urine, bilateral lower limb swelling, and puffiness on his face. For a month before his presentation, he had many bilateral skin lesions on his lower limbs that were leaking pus.

Objective: Traditional initial treatment regimens for lupus nephritis (LN) used oral glucocorticoids (GC) in starting doses up to 1.0 mg/kg/day prednisone equivalent with or without a preceding intravenous methylprednisolone pulse. More recent management guidelines recommend lower starting oral GC doses following intravenous pulse therapy.

Objective: Both belimumab and telitacicept are recognised blockers for B lymphocyte activation, both of which have been approved as add-on therapies for SLE in China. The aim of this study is to compare the efficacy of rituximab (RTX) followed by belimumab or telitacicept in a real-world cohort.
Methods: A total of 49 refractory lupus nephritis patients were enrolled from four independent centres, subsequently categorised into two treatment groups: belimumab group (n=35) and telitacicept group (n=14) based on their treatment following RTX.
Unlabelled: The management of proteinuria in patients with lupus nephritis represents a challenge for the specialist. Recently, Calcineurin Inhibitors have been positioned as an effective alternative in these patients, but their use is not widespread in our country. We report the experience of three centers in this regard.

Systemic lupus erythematosus (SLE) is an autoimmune disease that more commonly affects African American people, although it is seen in people of all racial backgrounds. This condition is characterized by a dysregulated immune response resulting in widespread inflammation. Clinical manifestations caused by this inflammation include arthritis, anemia, cutaneous rashes, pleuritis, and nephritis.
