Increased Incidence of Invasive Fusariosis with Cutaneous Portal of Entry, Brazil

Most cases of infection with Fusarium spp. fungi involved primary skin lesions.

Superficial mycoses in immunodepressed patients (AIDS)

HIV infection has the capacity to distort the epidemiology and clinical course of infectious diseases, producing atypical manifestations and changing diagnoses. Superficial fungal infections are frequent in HIV-positive/AIDS patients and are no exception. These infections are frequently different in immunodepressed patients (AIDS), with a modified course or exacerbations. This chapter discusses the diagnosis and treatment of superficial mycoses in HIV patients, including cutaneous alterations caused by Candida, dematiaceous fungi agents of phaeohyphomycosis, Malassezia spp, dermatophyte, and filamentous nondermatophyte fungi.

Systemic mycoses in immunodepressed patients (AIDS)

Infectious and noninfectious skin diseases are observed in about 90% of HIV patients, and their incidence increases and is more severe as the immune system weakens. Cutaneous manifestations are considered good clinical predictors for the immunological condition of the patient with AIDS and the introduction of highly effective antiretroviral therapy totally changed the prognosis of the mycoses, among other diseases associated with AIDS, permitting longer survival and acceptable level of quality of life for these patients. This contribution describes the systemic mycoses that are more frequent in the seropositive population, that is, patients with HIV/AIDS, which are cryptococcosis, histoplasmosis, coccidioidomycosis, blastomycosis, paracoccidioidomycosis, sporotrichosis, penicilliosis, and aspergillosis. Their causative agents, mode of transmission, clinics, laboratorial diagnosis and therapy, in the aspects related to immunodepressed patients, are reviewed.

Bacillary angiomatosis: description of 13 cases reported in five reference centers for AIDS treatment in Rio de Janeiro, Brazil

The aim of this case series was to describe the clinical, laboratory and epidemiological characteristics and the presentation of bacillary angiomatosis cases (and/or parenchymal bacillary peliosis) that were identified in five public hospitals of Rio de Janeiro state between 1990 and 1997; these cases were compared with those previously described in the medical literature. Thirteen case-patients were enrolled in the study; the median age was 39 years and all patients were male. All patients were human immunodeficiency virus type 1 (HIV-1) infected and they had previous or concomitant HIV-associated opportunistic infections or malignancies diagnosed at the time bacillary angiomatosis was diagnosed. Median T4 helper lymphocyte counts of patients was 96 cells per mm(3). Cutaneous involvement was the most common clinical manifestation of bacillary angiomatosis in this study. Clinical remission following appropriate treatment was more common in our case series than that reported in the medical literature, while the incidence of relapse was similar. The frequency of bacillary angiomatosis in HIV patients calculated from two of the hospitals included in our study was 1.42 cases per 1000 patients, similar to the frequencies reported in the medical literature. Bacillary angiomatosis is an unusual opportunistic pathogen in our setting.

Sporotrichosis with Bone Involvement: An Alert to an Occupational Disease

Sporotrichosis is a subacute or chronic mycosis caused by a fungus of the genus Sporothrix, which is found in soil. It can be acquired by trauma to the skin. Bone and joint lesions are very rare. The city of Rio de Janeiro is undergoing an epidemic transmitted by cats, and this should be an alert for the risk to professionals in contact with these animals. The patient was a veterinarian who developed occupational sporotrichosis with osteoarticular involvement transmitted by a cat during a consultation.

Antimold Prophylaxis May Reduce the Risk of Invasive Fusariosis in Hematologic Patients with Superficial Skin Lesions with Positive Culture for Fusarium

ABSTRACT Hematologic patients with superficial skin lesions on admission growing Fusarium spp. are at a high risk for developing invasive fusariosis during neutropenia. We evaluated the impact of primary prophylaxis with a mold-active azole in preventing invasive fusariosis in these patients. Between August 2008 and December 2014, patients with acute leukemia or aplastic anemia and recipients of hematopoietic cell transplants were screened on admission with dermatologic and direct exams and fungal cultures of superficial skin lesions. Until November 2009, no interventions were made. Beginning in December 2009, patients with baseline skin lesions and a direct exam and/or culture suggestive of the presence of Fusarium spp. received prophylaxis with voriconazole or posaconazole. Skin lesions in the extremities (mostly onychomycosis and interdigital intertrigo) were present on admission in 88 of 239 episodes (36.8%); 44 lesions had hyaline septate hyphae identified by direct exam, and cultures from 11 lesions grew Fusarium spp. Antimold prophylaxis was given for 20 episodes (voriconazole for 17 and posaconazole for 3). Invasive fusariosis was diagnosed in 14 episodes (5.8%). Among patients with baseline skin lesions with positive cultures for Fusarium spp., 4 of 5 without antimold prophylaxis developed invasive fusariosis versus 0 of 6 with antimold prophylaxis (P = 0.01; 95% confidence interval for the difference between proportions, 22% to 96%). Primary antifungal prophylaxis with an antimold azole may prevent the occurrence of invasive fusariosis in high-risk hematologic patients with superficial skin lesions on admission growing Fusarium spp.

An index for staging facial lipoatrophy and evaluation of the efficacy of the treatment with polymethylmethacrylate in HIV/AIDS patients: a pilot study

Background  Treatment of facial lipoatrophy of HIV/AIDS patients is mandatory by law in Brazil due to its negative impact on their quality of life. The index for facial lipoatrophy (ILA) is used as one of the inclusion criteria for patient treatment.

Paradoxical Reaction to Golimumab: Tumor Necrosis Factor α Inhibitor Inducing Psoriasis Pustulosa

Importance: Golimumab is a human monoclonal antibody, used for rheumatoid arthritis, psoriatic arthritis and ankylosing spondylitis. Adverse reactions are increasing with this class of medication (tumor necrosis factor α inhibitors). Observations: The authors present a case of a female patient who presented with psoriasis pustulosa after the use of golimumab for rheumatoid arthritis. Conclusions and Relevance: Paradoxically, in this case, golimumab, which is used for psoriasis, induced the pustular form of this disease. We are observing an increasing number of patients who develop collateral effects with tumor necrosis factor α inhibitors, and the understanding of the mechanism of action and how these adverse reactions occur may contribute to avoid these sometimes severe situations.

Granulomatous slack skin. Histopathology diagnosis preceding clinical manifestations by 12 years.

BACKGROUND Granulomatous slack skin is a very rare subtype of T-cell cutaneous lymphoma, characterized by the slow development of cutaneous sagging, especially on flexural areas. Its behavior is indolent and the treatment, in the majority of cases, disappointing. MAIN OBSERVATION We report a 54-year-old black patient with granulomatous slack skin, who at the beginning of the investigation showed intense xeroderma and generalized lymph node enlargement. The diagnosis was established based on histopathologic findings long before the diseases characteristic clinical presentation appeared. CONCLUSIONS During the twelve years of follow-up, the clinical manifestation evolved to marked skin looseness, most predominant in flexural regions, illustrating the clinical hallmark of granulomatous slack skin, long after first histological abnormalities were observed.

Human papillomavirus detection and typification in cutaneous and mucosal lesions of HIV-seropositive patients.

Summary: High-risk human papillomavirus (HPV) in a lesion is related to an increased chance of neoplasic transformation, especially when with immunosuppression, as in HIV infection. We investigated HPV frequency in cutaneous and mucosal lesions of HIV-seropositive male patients. The frequency of malignancy, its association with the HPV type detected and some clinical variables were also assessed. A total of 38 lesions from 27 patients were studied in a period of 18 months. The biopsied fragment was submitted to HPV detection and typification, through polymerase chain reaction with generic (MY09/11) and specific (types 6, 11, 16 and 18) primers. HPV frequency was 63.2%, with detection of HPV types 6, 11 or 16 in 18 lesions and with multi-infection in three. There was low detection of high-risk HPV (type 16, 18.4%) and no HPV type 18. Of the lesions, 36.8% were already premalignant or malignant, and the frequency of moderate or severe dysplasia was higher in the study patients than that described in the HIV-seronegative population. High-risk HPV (type 16) was detected in four benign lesions and low-risk HPV (type 6) in three premalignant genital lesions. There was no significant association between the clinical variables and an increase in the prevalence of premalignant or malignant lesions.
