Clinical characteristics, diagnosis, and treatment of central nervous system sporotrichosis: Systematic review and meta-analysis.

BACKGROUND: The clinical features of central nervous system (CNS) sporotrichosis are derived from case reports and a limited series of cases. Our objective was to carry out a systematic review and meta-analysis of CNS sporotrichosis. METHODS: We searched PubMed/MEDLINE, Embase, Scopus, and LILACS on 9 September 2023. Our inclusion criteria were documentation of Sporothrix and demonstrated CNS involvement. A metaproportion or metamean analysis was performed to estimate a summary proportion with 95% confidence intervals. RESULTS: We included 52 cases of CNS sporotrichosis published from 1966 to 2023. Forty-six patients were male (88%, 95% CI: 77-95), and the mean age was 39 years (95% CI: 36-43). Close contact with cats was reported in 55% of cases (95% CI: 37-72). Thirty-two (61.5%) patients were from Brazil, 18 patients from the United State of America (34.6%). Only two Sporothrix species were reported: S. schenckii (26/41, 63%), and S. brasiliensis (15/41, 37%). The most common neurological symptom was headache. Meningitis was chronic in approximately 80% of cases. A significant majority of the patients were immunocompromised. HIV infection was the primary cause of immunosuppression (85%, 95% CI: 61-95). Overall mortality was 56% (22/39). The comparison of Kaplan-Meier survival curve showed a higher mortality with a statistically significant difference in immunosuppressed patients (p = .019). CONCLUSION: CNS sporotrichosis represents a notable cause of chronic meningitis, especially in individuals living in the Americas with HIV infection and concurrent skin lesions.

Feline sporotrichosis due to Sporothrix globosa in the Metropolitan region of Buenos Aires: A case study.

We describe here the first case of feline sporotrichosis caused by Sporothrix globosa, occurring outside the epizootic area of Buenos Aires province, Argentina. Unlike cases reported with Sporothrix brasiliensis, on this occasion there was no clinical or serological evidence of zoonotic transmission through scratches or bites from the sick cat to the attending veterinarian or the person responsible for its care. This report aimed to improve the knowledge about the pathogenic profile of S. globosa.

Photodynamic therapy in the coadjuvant treatment of Sporothrix schenckii complex.

INTRODUCTION: Sporotrichosis, a zoonosis caused by animal, mainly cat, scratches or bites, is caused by fungi belonging to the Sporothrix complex. Treatment usually consists in antifungal administration, although treatment failure and hepatotoxicity reports have been noted. Alternative sporotrichosis treatment methods, such as antimicrobial photodynamic therapy (aPDT), may, therefore, be indicated. CASE REPORT: In this context, this study followed a 56-year-old male renal transplanted patient displaying disseminated sporotrichosis, presenting erythematous skin lesions with ulcerated backgrounds and hardened consistency on the nose, oral and scalp. The lesions were present for about 2 months and the patient coexisted with cats. Intravenous amphotericin B administration was initiated, and immunosuppression was suspended. Seven aPDT sessions were also performed in 48 h intervals on the oral lesions, employing 0.01% methylene blue gel as the photosensitizing agent. After the 4th aPDT session, the patient was discharged, amphotericin B administration was suspended, and the treatment was continued with itraconazole, without immunosuppression. Red laser was applied to the oral lesions after the 7th aPDT session. Significant lesion improvement was observed after the final aPDT session and complete palate lesion repair was noted after two red laser sessions. CONCLUSION: These findings indicate that aPDT is a valuable strategy as an adjunct sporotrichosis treatment.

Hyperthermia is a promising potential adjunct to treating sporotrichosis: A refractory case of HIV sporotrichosis and in vitro experiments on Sporothrix spp.

BACKGROUND: Hyperthermia is a common monotherapy for sporotrichosis, but only in patients with special conditions, such as pregnancy and nursing. However, hyperthermia has not been used more widely for sporotrichosis in clinical practice. PATIENTS/METHODS: An HIV-positive adult male with lymphocutaneous sporotrichosis caused by Sporothrix globosa that did not respond to conventional itraconazole therapy lasting >2 months received adjunctive therapy with local hyperthermia. To simulate the effects of heat exposure on the growth and morphology of Sporothrix spp. in vitro, S. globosa, S. schenckii and S. brasiliensis were exposed to intermittent heat (42°C) for 1 h a day for 7 or 28 days and observed under transmission electron microscopy. RESULTS: Itraconazole combined with local hyperthermia significantly improved the lesions, and the patient was successfully cured of sporotrichosis, with no recurrence after 2 years of follow-up. Cultures of Sporothrix spp. treated with 7 days of daily heat exposure in vitro showed obvious decreases in colony diameters, but not numbers, compared with untreated cultures (p < .001). After 28 days of heat exposure in vitro, Sporothrix spp. were unable to thrive (p < .001), and ultrastructural alterations, including loose cell wall structure, incomplete cell membrane, disrupted vacuoles and fragmented nuclei, were noticeable. CONCLUSIONS: Our case findings and in vitro experiments on Sporothrix spp., together with a literature review of previous sporotrichosis cases, suggest that hyperthermia has a clinical role as a treatment adjunct. Large-scale clinical trials are required to examine the utility of hyperthermia in various forms of cutaneous sporotrichosis.

Intramedullary disseminated sporotrichosis in an immunocompetent patient: case report and review of the literature.

BACKGROUND: Disseminated sporotrichosis is a severe opportunistic infection that often affects immunocompromised patients after a cutaneous inoculation. Here we present a rare case of disseminated sporotrichosis discovered as a solitary intramedullary thoracic spinal cord lesion in an immunocompetent patient. CASE DESCRIPTION: A 37-year-old man presented with progressive lower limb weakness and sensory changes over 1 week. A spinal magnetic resonance imaging (MRI) revealed a contrast-enhancing intramedullary lesion centered at T10. The patient was afebrile and reported no history of trauma or cutaneous lesions. The lesion was unresponsive to a trial of corticosteroids. A thoracic laminectomy was performed and a biopsy obtained. A cutaneous lesion on the arm was concurrently discovered, which was also biopsied. Both the skin and spinal cord biopsies showed Sporothrix schenckii by macroscopic and microscopic morphology which were later confirmed by MALDI-TOF mass spectrometry. CONCLUSION: This is a rare case of intramedullary disseminated sporotrichosis affecting the central nervous system of an immunocompetent patient. This unusual presentation should be taken into consideration when such intramedullary lesions are encountered.

A Case of Disseminated Cutaneous Sporotrichosis Mimicking Sarcoidosis, that Required Four Biopsies to Diagnose.

A 69-year-old Japanese woman visited Tokai University Oiso hospital with cutaneous ulcers on her left upper arm that appeared in January 2013, and on her right nose that appeared in December of 2013. Neither the two biopsies and tissue culture from the arm lesion nor the biopsy and tissue culture from the nose lesion detected any organism. In December of 2013, she was diagnosed as cutaneous sarcoidosis at Oiso hospital and treated with oral prednisolone for six months, however, did not show improvement. In June of 2014, third skin biopsy and culture from her left upper arm was done at our hospital, and also could not detect any organism. After six months of continuing treatment with oral steroids and steroid injections, the cutaneous ulcers became enlarged, with purulent exudate, requiring a fourth skin biopsy and culture from left upper arm, which finally detected Sporotrichosis. After one-month administration of itraconazole, in January of 2015, cutaneous ulcers of both the arm and nose shrunk. Sporotrichosis mimics sarcoidosis as well as other skin conditions clinically and histologically, therefore recognizing the importance of carrying out multiple skin biopsies and cultures are imperative to prevent misdiagnosis and improper treatments and possible dissemination.

Cutaneous Sporothrix globosa infection mimicking cryptococcosis in a patient with history of kidney transplant.

Sporotrichosis is a subacute-to-chronic infection caused by Sporothrix species, a dimorphic fungus. Virulence varies by Sporothrix species and presentation can be region dependent. The patient had a history of immunosuppression as a result of a kidney transplant, and presented with a high disease burden on histopathological examination, but responded well to itraconazole. The case suggests considering Sporothrix speciation in immunocompromised patients to best determine treatment modality and duration.

Tuberculosis cutánea esporotricoide en la Amazonía peruana: reporte de caso / Sporotrichoid cutaneous tuberculosis in the peruvian amazon: case report

RESUMEN La tuberculosis cutánea es una presentación rara de la infección por Mycobacterium tuberculosis. Se presenta el caso de una mujer sin antecedentes médicos de importancia, con un tiempo de enfermedad de año y medio, caracterizado por lesiones tipo esporotricoide, con diseminación linfocutánea en miembro superior derecho, de evolución lentamente progresiva. Se realizó un estudio histopatológico encontrándose células gigantes tipo Langhans y escasa necrosis. El paciente recibió terapia de esquema sensible antituberculoso, con evolución favorable.

ABSTRACT Cutaneous tuberculosis is a rare presentation of Mycobacterium tuberculosis infection. We present the case of a woman without important medical history, with a disease period of one year and a half, characterized by sporotrichoid-like lesions, with lymphocutaneous dissemination in the right upper limb, and with slowly progressive evolution. The histopathological tests revealed Langhans type giant cells and scarce necrosis. The patient received therapy with a sensitive antituberculous scheme, and evolved favorably.

Differential recognition and cytokine induction by the peptidorhamnomannan from Sporothrix brasiliensis and S. Schenckii.

Sporotrichosis is a deep mycosis caused by dimorphic species of the genus Sporothrix, with differences in pathogenicity between S. schenckii and S. brasiliensis species. Recently, it was discovered that the cell wall peptidorhamnomannan (PRM) from S. brasiliensis has additional unknown rhamnose residues. We hypothesize that the structural differences of Sporothrix spp PRMs impact the host's immune response and may explain the severity of sporotrichosis caused by S. brasiliensis. We demonstrate that S. brasiliensis yeasts and its PRM (S.b PRM) induced a strong inflammatory response in human PBMCs, with high production of TNF-α, IL-6 and IL-1ß and induction of T-helper cytokines IFN-γ, IL-17 and IL-22. In contrast, S. schenckii yeasts and its PRM induced higher concentrations of interleukin-1 receptor antagonist (IL-1Ra), which resulted in low production of T-helper cytokines such as IL-17 and IL-22. CR3 and dectin-1 were required for cytokine induction by both PRMs, while TLR2 and TLR4 were required for the response of S.s PRM and S.b PRM, respectively. IL-1ß and IL-1α production induced by S. brasiliensis yeasts and S.b PRM were dependent on inflammasome and caspase-1 activation. S. schenckii and S.s PRM were able to induce IL-1ß independent of ROS. In conclusion, these findings improve our understanding of the pathogenesis of Sporothrix spp. by reporting differences of immunological responses induced by S. schenckii and S. brasiliensis. The study also opens the gateway for novel treatment strategies targeting local inflammation and tissue destruction induced by S. brasiliensis infection through IL-1 inhibition.

Sporothrix schenckii regulates macrophage inflammatory responses via the c-JUN-induced Dab2 transcription.

Macrophages, which serve as a bridge between innate and adaptive immunity, play an important role in sporotrichosis. Sporothrix schenckii infections can produce immune responses such as macrophage polarization and inflammatory factor secretion. In the early stages of inflammation, the expression of DAB2 in macrophages is increased, which controls the secretion of inflammatory factors and affects the polarization of macrophages. However, the expressions and mechanisms of DAB2 in sporotrichosis are not clear. In this study, we examined the expression of DAB2 and its regulation of inflammatory factors under conditions of Sporothrix schenckii infection. Our results indicated that the Sporothrix schenckii infection increased the expression of DAB2 and revealed a mixed M1/M2-like type of gene expression in BMDMs with the inhibited Il-6, Il1-ß and Arg-1 and induced Tnf-α, Il-10 and Mgl-1. The deficiency of Dab2 gene suspended the changes of cytokines. In addition, JNK activity in BMDMs was inhibited by Sporothrix schenckii infection, leading to an increase in c-JUN. We also identified c-JUN as a transcription factor for Dab2 through chromatin immunoprecipitation and luciferase reporter assays. In an in vivo mouse model, sporotrichosis-induced skin lesions were accompanied with an upregulation of c-JUN and inhibition of JNK activity, which were in accord with findings from in vitro experiments. Taken together, these findings indicate that in the early stages of Sporothrix schenckii infection there is a promotion of DAB2 expression through the JNK/c-JUN pathway, effects that can then control the expression of inflammatory factors.

Refractory feline sporotrichosis: a comparative analysis on the clinical, histopathological, and cytopathological aspects / Esporotricose felina refratária: uma análise comparativa sobre os aspectos clínico, histopatológico e citopatológico

Sporotrichosis is a chronic fungal infection caused by Sporothrix species. The occurrence of cases that are resistant to long-term treatment, especially in the nasal planum of cats, emphasizes the importance of studying its pathogenesis. The purpose of this study was to analyze and compare the inflammatory process of cutaneous lesions of feline refractory sporotrichosis to clinical aspects through cytopathological and histopathological examination. Moreover, the study included 13 cats with cutaneous lesions that had been resistant to itraconazole treatment for more than a year. Cutaneous lesions samples were collected for cytopathological, histopathological, and fungal culture analyses. Tissue fragments were processed and stained with hematoxylin-eosin (HE) and Grocott methenamine silver (GMS). Further, two clinical presentations had the highest occurrence: the localized cutaneous form in animals with good general condition and stable disease (n=9, 69.2%) and the disseminated cutaneous form in cats with poor general condition (n=4, 30.8%). In cats with refractory sporotrichosis, the nasal planum (84.6%) was the most common location of lesions. In the cytopathological study, cats with fewer than two lesions and in good general condition (n=9, 69.2%) showed absence or mild yeast intensity (up to 5 yeasts per field), lower intensity of macrophages and neutrophils, and higher intensity of epithelioid cells, lymphocytes, plasma cells, and eosinophils. On the other hand, (n=4, 30.8%) of the cats with disseminated sporotrichosis and a poor general condition had a marked intensity of yeasts, which were mostly phagocytosed by an increased number of macrophages and neutrophils. Of those animals with good general condition, the majority (n=6, 66.7%) had higher eosinophil intensity. In histopathology, malformed suppurative granuloma was the predominant type (n=9, 69.2%) in feline sporotrichosis lesions, followed by well-formed granulomas (n=4, 30.8%). Malformed granulomas showed mild to moderate fungal intensity (55.6%) in animals with good general condition and localized lesions while marked fungal intensity (44.4%) in cats with the disseminated form of the disease and poor general condition. Well-formed granulomas (n=4, 30.7%) had mild to moderate intensity of fungal load, and 75% of the animals with this type of granuloma had only one lesion and were in good general condition. Long-term itraconazole treatment in these cats with refractory sporotrichosis can keep the infection under control and localized lesions stable; however, fungus reactivation can occur, resulting in an exuberant and inefficient immune response.(AU)

A esporotricose é uma infecção fúngica crônica causada por espécies do gênero Sporothrix. A ocorrência de casos refratários ao tratamento de longo prazo, especialmente na região nasal de gatos, alerta para a importância do estudo de sua patogênese. Este estudo teve como objetivo analisar o processo inflamatório das lesões cutâneas de esporotricose felina refratária ao tratamento, por meio de exames citopatológico e histopalógico, e comparar com aspectos clínicos. Treze gatos com lesões cutâneas refratárias ao tratamento com Itraconazol por mais de um ano foram incluídos no estudo. Amostras de lesões cutâneas foram coletadas para análises citopatológicas, histopatológicas e cultura fúngica. Fragmentos de tecidos foram processados e corados pela hematoxilina-eosina (HE) e Prata Metenamina de Grocott (GMS). Duas apresentações clínicas tiveram maior ocorrência: a forma localizada cutânea em animais com bom estado geral e doença estável (n=9, 69,2%); e a forma disseminada cutânea em gatos com estado geral ruim (n=4, 30,8%). A região nasal (84,6%) foi a localização mais frequente das lesões nos gatos com esporotricose refratária ao tratamento. No estudo citopatológico, felinos com menos de duas lesões, e em bom estado geral, (n=9, 69,2%) revelaram ausência ou leve intensidade de leveduras (até 5 leveduras por campo), menor intensidade de macrófagos e neutrófilos, e maior intensidade de células epitelióides, linfócitos, plasmócitos e eosinófilos. Enquanto, (n=4, 30,8%) dos felinos que apresentavam a forma disseminada da esporotricose associada a um estado geral ruim, revelaram acentuada intensidade de leveduras em sua maioria fagocitadas por acentuado número de macrófagos e neutrófilos. Dos animais com bom estado geral, a maioria (n=6, 66,7%) apresentava maior intensidade de eosinófilos. Na histopatologia, o granuloma supurativo mal formado foi o tipo predominante (n=9, 69,2%) nas lesões de esporotricose felina, e (n=4, 30,8%) foram de granulomas bem formados. Granulomas mal formados apresentaram leve a moderada intensidade fúngica (55,6%) nos animais com bom estado geral e lesões localizadas, e acentuada intensidade fúngica (44,4%) nos gatos com a forma disseminada da doença e estado geral ruim. Granulomas bem formados (n=4, 30,7%) apresentaram leve a moderada intensidade de carga fúngica, sendo 75% dos animais com esse tipo de granuloma com apenas uma lesão e bom estadogeral. O tratamento de longo prazo com itraconazol, nesses gatos com esporotricose refratária, pode manter a infecção controlada e lesões localizadas estáveis de forma temporária, contudo a reativação do fungo pode ocorrer levando a uma resposta imunológica exuberante e ineficiente.(AU)

Can cats cause colossal contagious cutaneous carbuncles?

Sporothrix spp. cause the most common deep fungal skin infections in Brazil and this is related to infected cats. Transmission is traditionally from organic material/plants but can also be zoonotic. Culture of a skin biopsy is the golden standard for determination. Treatment with oral itraconazole approaches up to 95% efficacy in patients with cutaneous sporotrichosis.

Bone sporotrichosis: 41 cases from a reference hospital in Rio de Janeiro, Brazil.

BACKGROUND: Bone sporotrichosis is rare. The metropolitan region of Rio de Janeiro is hyperendemic for zoonotic sporotrichosis and the bone presentations are increasing. METHODS: We studied a retrospective cohort of 41 cases of bone sporotrichosis, diagnosed from 1999-2016. The inclusion criteria was fungal culture isolation from any clinical specimen associated to bone involvement (radiography and/or computed tomography) compatible with fungal osteomyelitis or histopathological findings of bone material compatible with sporotrichosis. Molecular identification was performed when possible. RESULTS: Male patients represented 58.5% of the cases, with a cohort median age of 43 years. Immunosuppressive conditions were present in 68.3% of the patients, mostly HIV coinfection (51.2%). Multifocal bone involvement (more than one anatomical segment) was diagnosed in 61% of the patients, while 39% presented unifocal involvement. The bones of the hands were the most affected (58.5%), followed by the feet (41.5%) and tibia (26.8%). Multifocal group was characterized by a higher proportion of males (p = 0.0045) with immunosuppressive conditions (p = 0.0014). Amphotericin B followed by oral itraconazole was the main treatment, with a median time of 16.7 months (1.5 to 99.2 months), and cure of 53.7% of the patients (84.6% of immunocompetent and 39.3% of immunocompromised patients). Sequelae occurred in 12.2% of the patients-amputations (7.3%) and ankylosis (4.9%), while 22% died in the course of the disease. Sporothrix brasiliensis was the causative agent in all the 9 (22%) performed cases. CONCLUSIONS: Bone sporotrichosis is a chronic, challenging condition with prolonged treatment, often with poor results and sequelae.

The clinico-epidemiological characteristics and therapeutic experience of 152 patients with cutaneous sporotrichosis: a 10-year retrospective study from India.

BACKGROUND: Cutaneous sporotrichosis, a subcutaneous mycosis because of Sporothrix schenckii, is sporadic worldwide with local hyperendemic pockets. OBJECTIVES: To study clinico-epidemiological and therapeutic aspects of sporotrichosis in our clinic. METHODS: We retrospectively analyzed medical records of 152 (M:F 52:100) patients with cutaneous sporotrichosis managed during 2010-2019. RESULTS: All patients were involved in agricultural activities, and 63.2% were aged 21-60 years. Women outnumbered men by nearly two times. Fixed and lymphocutaneous sporotrichosis occurred in 54.6% and 43.4% patients, respectively. Only 2% of patients had multifocal sporotrichosis. Only 48% of patients imputed their disease to prior injuries. Extremities, upper in 53.9% and lower in 21% of patients, were mostly involved. Scrotum involvement in one patient was unusual. A mixed inflammatory infiltrate in 38.7%, chronic granuloma formation in 35%, and presence of spores in 48.9% biopsies was noted. S. schenckii grew on Sabouraud's dextrose agar in 40.2% of cases. Treatment with saturated solution of potassium iodide was curative in 76.8% patients, and lesions healed in 2-9 months (average 5.2 months). Metallic taste was experienced by 42.9% of patients. Itraconazole therapy was safe and effective in seven patients, and the response was better when combined with SSKI compared to either drug used alone. CONCLUSION: Cutaneous sporotrichosis mostly affects persons during active years of life. The injuries predisposing to infection are mostly forgotten. Both fixed and lymphocutaneous sporotrichosis involving extremities remain common forms. SSKI alone or in combination with itraconazole is safe and effective treatment. Itraconazole is preferable in patients having preexisting hypothyroidism or intolerance to SSKI.
