The ongoing glomerular damage of infections is not limited to the most widely known form of post-streptococcal glomerulonephritis, which is today less common in the Western world; other forms of glomerulonephritis are associated with several bacterial, viral and parasitic pathogens. The mechanisms responsible range from the direct damage of glomerular cells to the formation and deposition of immunocomplexes to molecular mimicry to the secretion of superantigens. Similarly, in the course of glomerular disease, infections are more frequent than in the general population due to the loss of immunoglobulins in urine and the immunosuppressive agents used to treat the autoimmune disease that decrease the activity of the immune system. Recognizing this two-way link, understanding its pathogenetic mechanism, and identifying the most appropriate therapeutic choice are essential for the personalized management of patients. In this continuously developing field, this short review summarizes the current state of the art as support for physicians, who are increasingly involved in managing patients with glomerular disease and infections.

Background: Pregnancy involves complex hemodynamic and immune adaptations to support the developing fetus. The kidney assumes a pivotal role in orchestrating these mechanisms. However, renal disease poses a potential risk for adverse maternal–fetal outcomes. While kidney function, hypertension, and proteinuria are recognized as key influencers of risk, the mere presence of glomerular disease, independent of these factors, may wield significant impact. Methods: A brief review of the existing literature was conducted to synthesize current knowledge regarding the interplay between glomerulonephritis and pregnancy. Results: The review underscores the centrality of the kidney in the context of pregnancy and highlights the role of glomerular disease, particularly when active. It emphasizes multifaceted risk modulators, including kidney function, hypertension, and proteinuria. Conclusion: Understanding the dynamics between pregnancy and glomerulonephritis is crucial for optimizing maternal and fetal outcomes. Preconception counseling and collaborative nephro-gynecological management emerge as pivotal components in addressing the unique challenges posed by this medical interplay.
