Disseminated herpes simplex virus (HSV) is mainly seen in immunocompromised individuals. Atypical lesions can be present in both primary infection and reactivation disease. Compared with the general population, inmunocompromised hosts are at greater risk of increased persistency and severity of clinical manifestations, including severe systemic involvement such as esophagitis, meningitis, and hepatitis. Herein, we report the case of a liver transplant recipient with atypical disseminated herpes simplex virus-1 complicated by HSV-related hepatitis...

Lactococcus garvieae is a relevant worldwide fish pathogen affecting various farmed and wild marine and freshwater species. It has also been isolated from other animals, such as ruminants with subclinical mastitis and pigs with pneumonia. From the early 90s, L. garvieae has been associated with different human infections, mainly endocarditis. During the last five years, human infections by this bacterium appear to be increasing, likely due to the improvement in microbiological methods for bacterial identification and the alertness of this bacterium by physicians...

Mucormycosis due to Lichtheimia ramosa is an infrequent opportunistic infection that can potentially be angioinvasive when affecting inmunocompromised hosts. We present a fatal case of mucormycosis, affecting a 56-year-old male with diabetes mellitus and siderosis, initially admitted to our hospital due to an H1N1 infection. The subject's clinical condition worsened and he finally died because of a necrotizing bilateral pneumonia with disseminated mycotic thromboses due to Lichtheimia ramosa, which is an emerging Mucoralean fungus...

We here report a clinical case of a female patient presenting with a three-month history of a white onychodystrophic lesion of both hallux. The infection was due to a mold, identified as Curvularia lunata var aeria. The Curvularia gender is related to the production of phaeohyphomycosis, Curvularia lunata cause onychomycosis occasionally. The patient was treated with itraconazole 200mg/day, during six month with complete remission of the lesions. In conclusion, it is important to consider these fungi as causative agent of nail mycosis since the initial site of infection may be a pathway for systemic dissemination in inmunocompromised patients...

Majocchi's granuloma is a persistent supurative folliculitis, associated with a deep granulomatous reaction induced by dermatophytes. There are two clinical forms of Majocchi's granuloma: the superficial form that appears in healthy individuals after localized trauma; and the nodular form, which occurs in inmunocompromised patients. We present a case of nodular Majocchi's granuloma on the forearm of an immunocompetent patient. Microbiological culture and examination of a deep aspiration sample identified Trichophyton rubrum...

INTRODUCTION: The population of immunocompromised patients has increased in recent decades. Many of these patients eventually present infectious complications including pneumonia, which is a diagnostic that must to be prompt and accurate. OBJECTIVE: To review the basis of the diagnosis of pneumonia in the immunocompromised patient. Sorted by the methodology of Bayesian inference, very relevant in the diagnostic attribution, we review the main basis of the diagnosis of pneumonia of immunocompromised patients: the epidemiology, the clinical history including the type of immunosuppression that weigh the likelihood of attribution a priori of an etiologic agent, and finally, the findings in the image (or likelihood function)...

Pet ownership offers undisputed benefits to immunocompromised (IC) patients, however, it poses the risk for potentially serious zoonoses. Mechanisms of transmission and manifestation of major zoonotic infections in dogs and cats that may affect IC patients are described. We also provide updated international information and local data. Recommendations are given to choose and care for pets ensuring safe and responsible ownership. This will help to prevent, detect and treat infections timely.

Strongyloidiasis is caused by the roundworm Strongyloides stercoralis (S. stercoralis). It is uncommon in the Unites States, and most cases are brought by travelers who have visited or lived in South America or Africa. Individuals with an intact immune system may experience mild gastrointestinal symptoms or none at all. In contrast, those with a compromised immune system may develop a rapidly fatal infection, commonly referred to as hyperinfection syndrome or disseminated Strongyloidiasis. We present a 66-year-old inmunocompromised male with Pemphigus Foliaceus who was admitted to the intensive care unit in critical condition and in whom a skin biopsy prove to be the main tool in the diagnosis of Strongyloidiasis...

RATIONALE: Probiotic bacterial strains have been increasingly used in clinical practice as many health benefits result from their use. However, severe side effects such as bacteremia and fungemia have been reported in inmunocompromised patients and those with chronic disease. OBJECTIVE: The purpose of this study was to report the impact of probiotic supplementation on the mortality of mice undergoing carcinogenesis induction with 1,2-dimethylhydrazine (DMH). METHODS: Two treatment protocols were used...

We describe a case of pure red cell aplasia developing within two months after kidney transplant in a patient who was actively receiving immunosuppression. His hemoglobin was 9.5 g/dL and his reticulocyte count was 0%. WBC and platelet counts were normal and a bone marrow showed hypercellularity with normal myelocytic and megakaryocytic elements. The erythrocytic series was completely absent except for an increased number of giant proerythronormoblasts with cytoplasmic vacuolization. The titers for IgG and IgM for Parvovirus were negative...

BACKGROUND: Peritonitis is a very rare condition that has been found on inmunocompromised patients and patients on peritoneal dialysis. OBJECTIVE: To present one case of a patient with chronic abdominal pain that was found to have coccidioidomycosis. CASE PRESENTATION: 50 year old female with 6 months of intermittent abdominal pain referred to right upper quadrant, nausea and vomiting, without fever or jaundice. On physical exam she had pain localized to right upper quadrant...

Relatively rare, splenic abscess is difficult to diagnose and often fatal if left untreated. The disease is thought to be growing in frequency because of the increasing number of inmunocompromised patients. Several mechanisms for the development of splenic abscess may exist. Some studies demonstrate that prior splenic injury in addition to bacteraemia is required for a splenic abscess to occur. In our series, 9 non immunocompromised patients were identified to have this disease during a 6 years period. Pathogens isolated included Salmonella sp, Staphylococcus sp and Enterococcus sp...

In this paper, a cutaneous alternariosis is described. This is a strange opportunist infection with less than 100 cases. The patient was not VIH although inmunocompromised due to several factors: Malabsorption Syndrome, megaloblastic anemia secondary to gastrectomy and distal pancreatomy with gastrodigiunostomia due to gastric adenocarcinoma four years ago; splenectomied in the same operation, long treatment with hydantoin, and corticosteroids. The patient was managed in the internal medicine unit due to a problematic respiratory infection with cardiac rhythm disorder and progressive debility in lower limbs, together with cutaneous lesions in which "alternaria sp" was isolated by culture...

BACKGROUND: Pyomyositis is a bacterial infection of skeletal muscle. Although more commonly seen in the tropics, it is increasingly recognized in temperate regions. The age distribution for patients with so called "tropical" or "temperate" pyomyositis differs. Most cases of tropical pyomyositis are seen in otherwise healthy patients and mainly in children, while the majority of cases of temperate pyomyositis occur in inmunocompromised adults. AIM: To report a series of patients with pyomyositis...

The Herpes simplex Virus (HSV) resistance to acyclovir (ACV) occurs in a 5% of the inmunocompromised patients, approximately. The treatment with analogs of nucleosides, causes the appearance of resistent HSV-ACV stocks (ACVr) which can be produced by alteration in genes coding for the TK or the DNA-polymerase. A previous large-scale clinical study on ACVr HSV strains isolated from patients infected with human immunodeficiency virus indicated that 96% of ACVr HSV mutants were low producers of, or deficient in, TK activity (TK-), with 4% being TK mutants with an altered substrate specificity...

The study of the nosocomial infections of fungic origin has attained importance in the last years, due to the rise in the number of patients that are inmunocompromised and susceptible to suffer this kind of infection. The objective of the present study was to evaluate the frequency of filamentous fungi and yeast, present in the environment of the Intensive Care Unit, operating and newborn children rooms of the Hospital Universitario "Antonio Patricio de Alcalá" (HUAPA) from the city of Cumaná. Suere State, Venezuela...

Brain abscess (BA) as complication of sinusitis represent around 3% of the cases. Other suppurative intracraneal complications such as epidural abscess, subdural empyema and meningitis are more common than BA. The frontal and ethmoid sinuses form an integral part of anterior and to a lesser extent middle skull base to which the dura is intimately related. Thrombophlebitis of veins associated with paranasal sinuses is considered to be the main route of intracraneal spread of infection. However, osteitis is an uncommon mechanism that typically involves frontal sinus...

INTRODUCTION: Acute typhlitis is usually associated with severe immunosuppressive conditions. Initially described as closely associated with infantile myeloid leukaemia, its incidence increased along the last decade. DESIGN: retrospective review. PATIENTS: 12 immunodepressed patients affected of acute typhilis in our hospital between 1994 and 2001. Suspected diagnosis was established by clinical symptoms and abdominal CT findings, and was confirmed with pathological finding in the surgical specimen...
