Paracoccidioidomycosis should be differentiated from other opportunistic diseases in human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) patients who live in Latin America. Laboratory investigation can begin with serological tests, which are rapid and efficient. In the present study, double immunodiffusion (DID), counterimmunoelectrophoresis (CIEP) and an enzyme linked immunosorbent assay (ELISA) tests were assessed for the detection of anti-Paracoccidioides brasiliensis antibodies in 40 patients coinfected with HIV. The results were compared to those obtained for 75 non-HIV-infected patients with endemic paracoccidioidomycosis. Anti-P. brasiliensis antibodies were detected in 65% (DID), 79% (CIEP) and 95% (ELISA) of the patients with HIV/AIDS, significantly lower rates than those detected in cases of endemic paracoccidioidomycosis, which were 89%, 99% and 100%, respectively. The reactive sera of HIV-infected patients also showed lower anti-P. brasiliensis antibody titres than those of non-HIV-infected patients. Despite the lower intensity of the specific humoral response, serological tests are useful for the diagnosis of opportunistic paracoccidioidomycosis in the HIV/AIDS population. We suggest optimization of the laboratory diagnosis by combining the ELISA test with CIEP or DID.; UPDT - PN-DST

Published studies on the association between cancer and paracoccidioidomycosis consist either isolated cases or clinical data based on hospital cohorts of paracoccidioidomycosis. The frequency of neoplasia in series of >= 80 patients with paracoccidioidomycosis ranges from 0.16 to 14.1%, mean of 3.96%. There are only two retrospective controlled studies, one of them showing greater incidence of carcinoma in biopsy and necropsy samples of paracoccidioidomycosis (12 cases in 147 patients with the mycosis: 8.2%) than in the necropsies of the control group (320 cases in 7,302 necropsies: 4.9%). In the other, 22,409 autopsies were reviewed and 4,372 cases of cancer were found; of the 85 patients with paracoccidioidomycosis, 12 were diagnosed with cancer. No differences were observed in the frequency of malignancies between the group of patients with paracoccidioidomycosis (14.1%) and the control group (19.5%). Considering all the reported cases, carcinoma was more frequent than hematological malignancies, and was more often found at the same site or in a neighboring site affected by the mycosis, usually occurring after the diagnosis of the mycosis. Commonly, the basic cause of death was related to secondary infections or neoplasia. Lymphoma was associated with poorly organized rich in fungi granuloma. The clinical course and mortality were related to the cancer evolution or secondary infections and was worse in lymphoid series...

Paracoccidioidomycosis is a systemic mycosis that is usually acquired early in life by inhalation of conidia which convert in the lungs into yeast forms; these in turn trigger an inflammatory process. This mycosis may appear as an acute/subacute form or a chronic, adult form. Acute/subacute presentations can be observed in children and young adults, with the reticuloendothelial system frequently involved but the lungs are usually spared or present with mild clinical or radiological alterations. Acute respiratory distress syndrome (ARDS), an extensive dysfunction of the lungs alveolar-capillary barrier has occasionally been observed in other endemic mycoses such as coccidioidomycosis, cryptococcosis, histoplasmosis and blastomycosis. We describe the first patient with acute paracoccidioidomycosis who developed fatal ARDS accompanied by multiple organ injuries. The basis of the rarity of this entity in patients with paracoccidioidomycosis, as well as the reasons that may have lead to the development of ARDS in this patient are discussed.

T-cell proliferative hypo responsiveness, a hallmark of paracoccidioidomycosis immune responses, underlies host`s failure in controlling fungus spread, being reversible with antifungal treatment. The mechanisms leading to this hypoproliferation are not well known. Since costimulatory molecules have been shown to profoundly regulate T-cell immune responses, we investigated the hypothesis that the determinants of the responder versus tolerant state may be the regulated expression of, or signaling by, costimulatory molecules. Expression of CD80, CD86, CD28, CD152, ICOS and PD-1 costimulatory molecules were examined on T-cells and monocytes harvested from stimulated and unstimulated PBMC cultures of active paracoccidioidomycosis patients and healthy individuals cured of past paracoccidioidomycosis. Stimuli were gp43, the immunodominant component of Paracoccidioides brasiliensis, and a Candida antigen. While CD28 expression, critical for optimal T-cell activation, was comparable between patients and controls, CD152, PD-1 and ICOS, which preferentially deliver negative signaling, were overexpressed on patients` stimulated and unstimutated T-cells. PBMC cultures were carried out in presence of the respective blocking antibodies which, however...

The conventional treatment for paracoccidioidomycosis, the most prevalent mycosis in Latin America, involves long periods of therapy resulting in sequels and high frequency of relapses. The search for new alternatives of treatment is necessary. Previously, we have demonstrated that the hsp65 gene from Mycobacterium leprae shows prophylactic effects against murine paracoccidioidomycosis. Here, we tested the DNAhsp65 immunotherapy in BALB/c mice infected with Paracoccidioides brasiliensis, the agent of paracoccidioidomycosis. We observed an increase of Th1 cytokines accompanied by a reduction in fungal burden and pulmonary injury. These results provide new prospects for immunotherapy of paracoccidioidomycosis and other mycoses. (C) 2009 Elsevier Ltd.

Objective. To investigate mortality in which paracoccidioidomycosis appears on any line or part of the death certificate. Method. Mortality data for 1985-2005 were obtained from the multiple cause-of-death database maintained by the Sao Paulo State Data Analysis System (SEADE). Standardized mortality coefficients were calculated for paracoccidioidomycosis as the underlying cause-of-death and as an associated cause-of-death, as well as for the total number of times paracoccidioidomycosis was mentioned on the death certificates. Results. During this 21-year period, there were 1950 deaths related to paracoccidioidomycosis; the disease was the underlying cause-of-death in 1 164 cases (59.69%) and an associated cause-of-death in 786 (40.31%). Between 1985 and 2005 records show a 59.8% decline in the mortality coefficient due to paracoccidioidomycosis as the underlying cause and a 53.0% decline in the mortality as associated cause. The largest number of deaths occurred among men, in the older age groups, and among rural workers, with an upward trend in winter months. The main causes associated with paracoccidioidomycosis as the underlying cause-of-death were pulmonary fibrosis, chronic lower respiratory tract diseases, and pneumonias. Malignant neoplasms and AIDS were the main underlying causes when paracoccidioidomycosis was an associated cause-of-death. The decision tables had to be adapted for the automated processing of causes of death in death certificates where paracoccidioidomycosis was mentioned. Conclusions. Using the multiple cause-of-death method together with the traditional underlying cause-of-death approach provides a new angle on research aimed at broadening our understanding of the natural history of paracoccidioidomycosis.

Once rare, septic shock (SS) due to disseminated fungal infections has been increasingly reported due to a growing number of immunocompromised patients, but remains rare in non-immune-compromised individuals. In paracoccidioidomycosis, it has been described in only three patients with the severe, acute form of the disease. We describe the development of a refractory, fatal septic shock due to a severe disseminated chronic form of paracoccidioidomycosis in an older woman without any other microbial insults. A striking event in the evolution of her case was the severe depletion of lymphocytes from the peripheral blood and lymphoid organs. Lymphocyte depletion due to apoptosis is described in the late phase of sepsis and can contribute both to immunosuppression and the progression of SS. The possible mechanisms involved in the induction of SS in the chronic form of paracoccidioidomycosis are discussed.

Às condições crônicas podem causar alterações físicas, psíquicas e sociais progressivas requerendo em alguns casos mudanças permanentes no estilo de vida dos indivíduos. A paracoccidioidomicose é uma micose sistêmica, que exige tratamento prolongado, cuja maior prevalência encontra-se na América Latina com diversas áreas endêmicas no Brasil. Este estudo teve como objetivo caracterizar os clientes portadores de paracoccidioidomicose cutânea mucosa e identificar os motivos da não adesão ao seguimento clínico terapêutico. Foram consultados 74 prontuários de clientes adultos com diagnóstico de paracoccidioidomicose cutâneo mucosa atendidos e ou internados em um hospital escola terciário do interior paulista, no período de janeiro de 2000 a junho de 2006. O projeto foi encaminhado ao Comitê de Ética em Pesquisa do referido hospital. A maioria dos sujeitos é do sexo masculino (86,5%), com idade médica de 44,5 anos, 67,6% dos casos foram internados de uma a oito vezes, em 50,0% dos casos a internação se deu em decorrência de recidivas e 74,3% fizeram uso irregular das medicações e houve o abandono do tratamento por 54% dos clientes.

INTRODUÇÃO: Micose sistêmica mais importante da América do Sul e do Brasil, a Paracoccidioidomicose acomete difusamente os pulmões no seu principal modo de apresentação, a forma crônica. Os pacientes podem apresentar anormalidades respiratórias com repercussão clínica e na qualidade de vida relacionada à saúde mesmo após tratamento antifúngico adequado. Não há, todavia, estudos que avaliem as alterações pulmonares radiológicas e funcionais e sua real incidência e repercussão clínica e na qualidade de vida desses pacientes após o tratamento. MÉTODOS: Análise transversal de 50 pacientes através de tomografia computadorizada de tórax, prova de função pulmonar completa, teste cardiopulmonar de esforço, teste de caminhada de seis minutos (TC6M) e questionário de qualidade de vida relacionada à saúde e de índice de dispneia. Todos tiveram diagnóstico da forma crônica da paracoccidioidomicose e foram avaliados quando atingiram critérios de inatividade de doença. RESULTADOS: Os pacientes apresentaram anormalidades tomográficas em 98% dos casos, sendo distorção da arquitetura (90%), reticulado (88%), enfisema centrolobular e parasseptal (84%) e bandas parenquimatosas (74%) as mais frequentes. Os achados foram principalmente difusos...

BACKGROUND: Paracoccidioidomycosis is a systemic mycosis of dermatological interest due to the frequency of cutaneous and mucosal lesions. The involvement of the external genitalia is extremely rare and few cases have been reported.OBJECTIVE: To study the prevalence of external genitalia lesions in paracoccidioidomycosis patients, identify clinical characteristics and compare with what is observed in the specific literature.METHODS: This is a cross-sectional, descriptive study, with focus on paracoccidioiodomycosis patients with external genitalia lesions. The demographic and clinical aspects of cases were compared with what has been reported so far on LILACS, SciELO e MEDLINE data bases.RESULTS: Data of 483 cases of paracoccidioidomycosis were studied in a 42-year period. Six (1.2%) patients showed specific lesions on external genitalia. Five patients were male with mean age of 47.2 years and all of them presented with the chronic multifocal clinical form. Only one, a 15-year-old female patient was observed who showed a subacute clinical form, juvenile type.CONCLUSIONS: Compromise of the genitourinary tract among paracoccidioidomycosis patients is rare and even rarer when only the external genitalia are considered. As observed in the classical picture of paracoccidioidomycosis patients...

Paracoccidioidomycosis is one of the most frequent systemic and endemic mycoses of Latin America caused by a dimorphic fungus. In AIDS patients, paracoccidioidomycosis appears as a severe and disseminated disease with a wide spectrum of clinical findings. The CD4 counts are usually less than 200 cell/mu L. We present a case of disseminated paracoccidioidomycosis with peripleuritis and subcutaneous abscesses on the chest wall as initial manifestation of AIDS. In endemic countries, paracoccidioidomycosis should be included as an opportunistic infection in AIDS.

Paracoccidioidomycosis should be differentiated from other opportunistic diseases in human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) patients who live in Latin America. Laboratory investigation can begin with serological tests, which are rapid and efficient. In the present study, double immunodiffusion (DID), counterimmunoelectrophoresis (CIEP) and an enzyme linked immunosorbent assay (ELISA) tests were assessed for the detection of anti-Paracoccidioides brasiliensis antibodies in 40 patients coinfected with HIV. The results were compared to those obtained for 75 non-HIV-infected patients with endemic paracoccidioidomycosis. Anti-P. brasiliensis antibodies were detected in 65% (DID), 79% (CIEP) and 95% (ELISA) of the patients with HIV/AIDS, significantly lower rates than those detected in cases of endemic paracoccidioidomycosis, which were 89%, 99% and 100%, respectively. The reactive sera of HIV-infected patients also showed lower anti-P. brasiliensis antibody titres than those of non-HIV-infected patients. Despite the lower intensity of the specific humoral response, serological tests are useful for the diagnosis of opportunistic paracoccidioidomycosis in the HIV/AIDS population. We suggest optimization of the laboratory diagnosis by combining the ELISA test with CIEP or DID.

The paracoccidioidomycosis mortality rate in the State of Paraná, Brazil (1980/1998) was analyzed using the death registry data from the Brazilian Mortality Information System and the estimated population from the Brazilian Institute of Geography and Statistics. To qualify the deaths, we deployed ICD-9 for 1980/1995 and ICD-10 for the more recent years. During this period there were 551 deaths from paracoccidioidomycosis in the State of Paraná. Most of the deaths were in male in the 30-59-year age group. The average annual mortality rate was 3.48 per million inhabitants, showing a tendency to stabilize during the study period. Paracoccidioidomycosis was the fifth cause of mortality among the predominantly chronic infectious diseases and had the highest mortality rate among the systemic mycoses. Paracoccidioidomycosis was observed in 184 counties in the State of Paraná. Most deaths were recorded in the North-Central meso-region, and the highest mortality rate occurred in the West meso-region.

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); Processo FAPESP: 2012/04850-6; This paper describes four new cases of lymphomas, two Hodgkin lymphomas and two non-Hodgkin lymphomas in patients with paracoccidioidomycosis. All had mycosis diagnosed before lymphomas with Paracoccidioides brasiliensis demonstrated in several lymph nodes, as seen in the disseminated form of the disease. When lymphoma was diagnosed, one patient was under regular paracoccidioidomycosis treatment and in clinic-serological remission for this disease, another was under regular treatment but with clinic-serological mycosis activity, one had abandoned paracoccidioidomycosis treatment 6 years earlier, and the other had not yet received any kind of antifungal drugs. Three patients received treatment for lymphomas with one remaining in remission until now, one achieving tumor remission which relapsed years later, and one having only residual lymphoma in bone marrow for a decade but clinically well. All three experienced paracoccidioidomycosis clinical remission, however, serology became negative just in one. Similar previously described cases were reviewed: five Hodgkin lymphomas, three non-Hodgkin lymphomas, and one described only as "lymphoma" without specifying type; a summary of their findings is presented. Finally...

Paracoccidioidomycosis is a systemic and endemic mycosis, restricted to tropical and subtropical areas of Latin America. The infection is caused by the thermal dimorphic fungus Paracoccidioides brasiliensisand Paracoccidioides lutzii. The diagnosis of paracoccidioidomycosis is usually performed by microscopic examination, culture and immunodiagnostic tests to respiratory specimens, body fluids and/or biopsies; however these methods require laboratory personnel with experience and several days to produce a result. In the present study, we have validated and evaluated a nested PCR assay targeting the gene encoding the Paracoccidioides gp43membrane protein in 191 clinical samples: 115 samples from patients with proven infections other than paracoccidioidomycosis, 51 samples as negative controls, and 25 samples from patients diagnosed with paracoccidioidomycosis. Additionally, the specificity of the nested PCR assay was also evaluated using purified DNA isolated from cultures of different microorganisms (n= 35) previously identified by culture and/or sequencing. The results showed that in our hands, this nested PCR assay for gp43 protein showed specificity and sensitivity rates of 100%. The optimized nested PCR conditions in our laboratory allowed detection down to 1 fg of P. brasiliensisDNA.

Despite their immunosuppressive effects, corticosteroids have long been used as adjunct therapy (aCST) in the treatment of infectious diseases. The rationale is that in certain infections it is necessary to decrease the exacerbated host's inflammatory response, which can otherwise result in tissue damage and organ dysfunction. In fact, a major concern in treating paracoccidioidomycosis (PCM) is the host's intense inflammatory response to Paracoccidioides brasiliensis, which can be further intensified by antifungal therapy. Depending on its localization, this immunological phenomenon may be life threatening or result in permanent sequels, as is the case for some patients with cerebral or laryngeal involvement. However, the literature on aCST in paracoccidioidomycosis treatment is scarce and as a result we present our recent experience in the management of four patients with severe PCM manifestations, i.e., cerebral paracoccidioidal granuloma, laryngeal stenosis, compressive abdominal mass, and exacerbated inflammatory response with tissue destruction. In addition to the antifungal therapy, these patients required aCST, which probably promoted their clinical improvement and/or prevented serious complications. We suggest that aCST: (a) can potentially help in the management of selected cases of severe forms of PCM...
