background and objectives: with increasing rate of immunodeficiency diseases in the world, opportunistic micro-organism such as pneumocystis jirovecii ( p. jirovecii ) become more important. little information is available on prevalence of this life- threatening microorganism in iran. this study was designed to determine the colonization and the rate of active disease caused by p. jirovecii in ...

background: cryptosporidium and isospora are known as one of the main cause of diarrhea in both immunocompetent and immunocompromised subjects, all over the world. incidence of enteropathogens such as cryptosporidium spp. and isospora belli considerably has increased, since immunodeficiency virus (hiv) rapidly disseminated. in addition, cancer patients are highly susceptible to opportunistic in...

abscess formation following intramuscular injections is rare and they are most commonly seen in immunocompromised individuals. in this case series we present a cohort of three patients presented to us in a critically ill condition with an abscess due to intramuscular injection. vancomycin resistant staphylococcus aureus was isolated from all three patients. these patients posed a major challeng...

Introduction: In HIV-associated tuberculosis cases, identifying nontuberculous Mycobacteria (NTM) from clinical samples has become essential regarding patients’ treatment and prognosis. This study aims to determine the prevalence of different Mycobacteria species from immunocompromised and immunocompetent patients with suspected tuberculosis attending a tertiary care hospital in Kolkata, India....

invasive gastric mucormycosis is a rare and fatal disease. we report a rare case with longstanding sle who presented with fever. autopsy showed multiple small shallow-based ulcers in the antrum. histologic examination showed invasive mucormycosis. this is a rare case of invasive gastric mucormycosis localized exelusively in the stomach.

Background Cryptococcosis is one of the major causes mortality among HIV patients worldwide. Though most often associated with late stage infection/AIDS, a significant number cases occur in other immunocompromised such as solid organ transplant recipients and hematological malignancies. Immunocompromised are heterogeneous group their increases constantly. Since little known about incidence clin...

Bacillary angiomatosis (BA) is a rare but an infrequent opportunistic infection reported mostly in HIV-infected patients. The most common site of involvement the skin manifestation followed by solid organs like liver and bone. Although cutaneous manifestations are treatable, other can be fatal some cases. We report case isolated osteolytic lesion due to (BA). conclude that should suspected scre...

BACKGROUND Five of 7 (71%) elderly immunocompetent patients with cytomegalovirus retinitis had retinal arteriolar occlusions versus 2 of 8 (25%) elderly immunocompromised patients and 1 of 19 (5%) younger HIV-infected patients. Compared to HIV-infected patients, elderly patients were more likely to have occlusive events, neovascularization or hemorrhage, and underlying vasculopathy. The purpose...
