Saprochaete clavata Infection in Immunosuppressed Patients: Systematic Review of Cases and Report of the First Oral Manifestation, Focusing on Differential Diagnosis

Fatal disseminated Magnusiomyces clavatus infection with rash in pediatric acute lymphoblastic leukemia: A case report

Magnusiomyces clavatus is a rare yeast-like fungus that can cause opportunistic infections in immunocompromised patients. Here, we present a 14-year-old patient who was followed up with the diagnosis of acute lymphoblastic leukemia, developed skin rashes, and Magnusiomyces clavatus infection detected. The patient died shortly after the infection was diagnosed.

Oral Candida and psoriasis: Is there association? A systematic review and trial sequential analysis

To assess (i) the prevalence of oral colonization by Candida spp. in patients with psoriasis and (ii) the prevalence of oral lesions associated with Candida spp. in patients with psoriasis and identify the risk factors for oral lesions. A systematic review was conducted in accordance with PRISMA criteria. The PROSPERO registration code is CRD42019127178. PubMed, Scopus and Web of Science were used as search engines. Meta-analyses and trial sequential analyses were performed. Among the 5805 retrieved records, nine articles were included. Among 530 psoriatic patients, 255 patients had an oral Candida spp. colonisation with an odds ratio (OR) = 3.44 (95% CI:2.38-5.00). Among 490 psoriatic patients, 43 patients developed oral Candida spp. lesions with an OR = 5.31 (95% CI:1.04-27.23). Among the patients without the main predisposing factors for infections, psoriatic patients had a higher OR (3.48, 95% CI: 2.0-6.0) for Candida spp. colonization, but not for Candida spp. infection, when compared with healthy controls (p-value > 0.05). Meta-analysis showed a higher risk of Candida spp. colonisation in patients with psoriasis. Patients who received immunosuppressive therapies were also at higher risk of developing oral lesions. Further studies are needed to understand these associations.

Saprochete capitata: Emerging Infections from Uncommon Microorganisms in Hematological Diseases

Infections occurring in immunocompromised patients after intensive chemotherapy are often difficult to eradicate and are capable of even being fatal. New emergent and dangerous drug-resistant micro-organisms are likely to appear in these specific scenarios. Clinical features mainly include progressive pneumonia, bacteriemia/fungemia, or extrapulmonary dissemination among infections. The treatment of these microorganisms is still an open challenge since there is a lack of clear treatment guidelines. Indeed, infections from these microorganisms can lead to a rapidly fatal clinical course in immunocompromised patients, especially those who have acute leukemia. We describe the case of a young patient with acute myeloid leukemia who contracted an infection from Saprochaete capitata during post-chemotherapy aplasia.

Septic shock due to co-infection with Legionella pneumophila and Saprochaete clavata

Septic shock is the most dreaded presentation of an infection, carrying a reserved prognosis. Appropriate antimicrobial therapy is therefore the mainstay of treatment, alongside organ support as needed. Legionnaires' disease is mainly due to Legionella pneumophila serogroup 1 but it can be caused by other serogroups and species not detected by the urinary antigen test. Anti-tumour necrosis factor α therapy may increase the risk of invasive fungal infection, which carry a poor prognosis. We present a challenging case of a septic shock due to Legionella pneumophila and Saprochaete clavata infections, with a review of the two infections presented.
