Granulomatous interstitial nephritis has been observed in <1% of native renal biopsies. Here, we describe two patients with granulomatous interstitial nephritis in relation to Crohn's disease. Circulating helper and cytotoxic T cells were highly activated, and both cell types predominated in the interstitial infiltrate, indicating a cellular autoimmune response. After immunosuppressive treatment, renal function either improved or stabilized in both patients. In conclusion, granulomatous interstitial nephritis is a genuine extraintestinal manifestation of Crohn's disease, the treatment of which should include immunosuppressive agents.

: ACE (angiotensin-converting enzyme) is considered a serological marker of sarcoidosis as elevated levels have been reported in 30-80% of patients. However, elevated ACE levels are also encountered in other medical conditions, and the clinical correlation between ACE levels and disease activity in sarcoidosis is disputable as well. To determine the significance of elevated ACE levels in the diagnosis and follow-up of sarcoidosis patients.

Common variable immunodeficiency (CVID) is a type of primary immunodeficiency that presents as a heterogenous disorder characterized by hypogammaglobinemia, poor response to vaccines, recurrent sinopulmonary infections, and can have noninfectious systemic manifestations. We performed a single-center, retrospective, observational study of five patients with noninfectious complications of CVID. All patients had CVID as defined by the European Society of Immunodeficiencies criteria and had received intravenous immunoglobulin therapy.

Background: While many studies have reported renal involvement in sarcoidosis, there is limited description of the pathological manifestations of renal sarcoidosis (RS). This study aimed to explore the standardized pathological diagnosis of RS while evaluating the relationship among pathology, clinical manifestations, and prognosis.

Methods: We conducted a retrospective, single-center study of RS in renal biopsy cases treated in our department between January 2019 and December 2023.
