She developed infectious loci in the lungs, hip, and brain. N. farcinica was detected in bronchoalveolar lavage and abscess culture. She was treated with linezolid, trimethoprim\/sulfamethoxazole (TMP\/SMX), minocycline, and amoxicillin\/clavulanic acid, achieving complete cure at 12 months. The second patient, a 73-year-old male with lupus nephritis V, autoimmune thrombocytopenia, antiphospholipid syndrome (APS), and alveolar hemorrhage, was treated with high-dose steroids, azathioprine, mycophenolate, and rituximab. He developed infections in the lungs, prostate, and possibly colon. N. farcinica was detected in blood cultures. Despite treatment with imipenem, linezolid, TMP\/SMX, and moxifloxacin, he died from bronchoaspiration.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A systematic review was conducted using PubMed, Embase, Web of Science, and Scopus.

Diagnosis requires a high level of clinical suspicion, supported by long-time blood cultures and 16S rRNA. Beta-lactams and quinolones are reasonable alternatives to TMP\/SMX and linezolid, which can worsen the hematological situation, and amikacin, which may worsen lupus nephritis.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/09612033251319836","type":"journal-article","created":{"date-parts":[[2025,2,27]],"date-time":"2025-02-27T06:45:41Z","timestamp":1740638741000},"page":"316-325","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Nocardiosis in systemic lupus erythematosus patients treated with rituximab: Report of two cases and systematic review of literature"],"prefix":"10.1177","volume":"34","author":[{"given":"Jaime","family":"Gil-Rodr\u00edguez","sequence":"first","affiliation":[{"name":"Departamento de Medicina Interna, Hospital Universitario Cl\u00ednico San Cecilio, Granada, Espa\u00f1a"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Javier de la Hera","family":"Fern\u00e1ndez","sequence":"additional","affiliation":[{"name":"Unidad de Enfermedades Autoinmunes Sist\u00e9micas, Hospital Universitario Cl\u00ednico San Cecilio, Granada, Espa\u00f1a"},{"name":"Instituto de Investigaci\u00f3n Biosanitaria ibs.GRANADA, Granada, Espa\u00f1a"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michel Martos","family":"Ruiz","sequence":"additional","affiliation":[{"name":"Departamento de Medicina Interna, Hospital Universitario Cl\u00ednico San Cecilio, Granada, Espa\u00f1a"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raquel R\u00edos","family":"Fern\u00e1ndez","sequence":"additional","affiliation":[{"name":"Unidad de Enfermedades Autoinmunes Sist\u00e9micas, Hospital Universitario Cl\u00ednico San Cecilio, Granada, Espa\u00f1a"},{"name":"Instituto de Investigaci\u00f3n Biosanitaria ibs.GRANADA, Granada, Espa\u00f1a"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marta Garc\u00eda","family":"Morales","sequence":"additional","affiliation":[{"name":"Unidad de Enfermedades Autoinmunes Sist\u00e9micas, Hospital Universitario Cl\u00ednico San Cecilio, Granada, Espa\u00f1a"},{"name":"Instituto de Investigaci\u00f3n Biosanitaria ibs.GRANADA, Granada, Espa\u00f1a"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9-Luis","family":"Callejas-Rubio","sequence":"additional","affiliation":[{"name":"Unidad de Enfermedades Autoinmunes Sist\u00e9micas, Hospital Universitario Cl\u00ednico San Cecilio, Granada, Espa\u00f1a"},{"name":"Instituto de Investigaci\u00f3n Biosanitaria ibs.GRANADA, Granada, Espa\u00f1a"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,2,27]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.3109\/08830185.2013.863305"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1080\/03009730802604931"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.mayocp.2011.11.016"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.diagmicrobio.2016.05.004"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1136\/bcr.11.2009.2421"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1002\/ajh.20921"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1111\/petr.13392"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1111\/dth.14601"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1473-3099(22)00344-9"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1080\/14397595.2020.1823070"},{"key":"e_1_3_2_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0049-0172(97)80003-0"},{"key":"e_1_3_2_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijsu.2021.105906"},{"key":"e_1_3_2_14_2","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-155-8-201110180-00009"},{"key":"e_1_3_2_15_2","first-page":"1","volume-title":"Cochrane Handbook for systematic reviews of interventions version 5.1.0","author":"Higgins J","year":"2011","unstructured":"Higgins J, Green S.
