Cellulitis Revealing a Cryptococcosis-Related Immune Reconstitution Inflammatory Syndrome in a Renal Allograft Recipient

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 12 2007
F. Lanternier
Immune reconstitution inflammatory syndrome (IRIS) has rarely been described in the course of disseminated cryptococcosis in solid organ transplant recipients. We report here the case of a renal transplant recipient who developed severe cellulitis in the context of Cryptococcus neoformans -associated IRIS while undergoing reduction of his immunosuppressive therapy. IRIS appeared concomitantly with a dramatic increase of blood CD4+ T cells (94,460/mm3) and required the administration of a short-term steroid therapy to resolve. [source]

AIDS-associated cryptococcosis: a comparison of epidemiology, clinical features and outcome in the pre- and post-HAART eras.

HIV MEDICINE, Issue 1 2009
Experience of a single centre in Italy
Objectives To assess the prevalence, clinical and immunological characteristics, risk factors and survival of patients with AIDS-related cryptococcosis in the era of highly active antiretroviral therapy (HAART). Methods All newly diagnosed cryptococcosis cases identified retrospectively from among a series of AIDS patients hospitalized consecutively at a single institution in Italy in 1985,1996 (pre-HAART period, n=165) and 1997,2006 (post-HAART period, n=40) were analysed comparatively. Results The prevalence of cryptococcosis decreased from 4.7% (165/3543) to 2.2% (40/1805) between the pre- and post-HAART periods (P=0.0001). There were no differences in the clinical features or immunological status of the patients between the two cohorts. The variables associated with the occurrence of cryptococcosis in the post-HAART era were older age (P<0.001), no previous diagnosis of HIV infection (P<0.001) and infection in homosexual males (P=0.004). During the post-HAART period, immune reconstitution inflammatory syndrome associated with cryptococcosis was observed in five patients (19.3%) a median of 15 weeks after the start of HAART. Thirty-day survival (P=0.045) and overall survival (P=0.0001) were significantly better among patients diagnosed with cryptococcosis in the post-HAART compared to those diagnosed in the pre-HAART era. Conclusions The AIDS-associated cryptococcosis observed in Western countries in the HAART era has similar clinical and immunological characteristics to that observed in the pre-HAART era, but a significantly better outcome.

Some unusual type 2 reactions in leprosy

INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 2 2010
V. Ramesh MD
Background, Type 2 reactions with lepromatous leprosy (LL) not occurring during multi-drug therapy (MDT) have been reported. Methods, Three patients have been described, each representing a prototype, the first presenting as bullous erythema nodosum leprosum (ENL), second with ENL erupting after treatment for co-existing pulmonary tuberculosis and resembling immune reconstitution inflammatory syndrome, and a third patient with recurrent Sweets-syndrome like presentation who had taken incomplete MDT in the past for leprosy. In all, the diagnosis was established by demonstration of acid-fast bacilli (AFB) on slit-skin smears (SSS) and histopathology. Results & Conclusion, The fact that reactions can occur in patients with clinically inapparent LL, who are more likely to present in general hospitals, has been reemphasized to enhance awareness among physicians. First presentation of leprosy as ENL is probably precipitated by common antibiotics taken for other illnesses. Since reactional episodes can occur before, during and after MDT for leprosy and the clinical picture is not specific to any of them, it is important to ascertain the status of anti-leprosy therapy during these episodes and treat them accordingly.

Chronic lung disease in human immunodeficiency virus (HIV) infected children,

PEDIATRIC PULMONOLOGY, Issue 1 2008
Heather J. Zar
Abstract The development of chronic lung disease is common in HIV-infected children. The spectrum of chronic HIV-associated lung disease includes lymphocytic interstitial pneumonia (LIP), chronic infections, immune reconstitution inflammatory syndrome (IRIS), bronchiectasis, malignancies, and interstitial pneumonitis. Chronic lung disease may result from recurrent or persistent pneumonia due to bacterial, mycobacterial, viral, fungal or mixed infections. In high tuberculosis (TB) prevalence areas, M. tuberculosis is an important cause of chronic respiratory illness. With increasing availability of highly active antiretroviral therapy (HAART) for children in developing countries, a rise in the incidence of IRIS due to mycobacterial or other infections is being reported. Diagnosis of chronic lung disease is based on chronic symptoms and persistent chest X-ray changes but definitive diagnosis can be difficult as clinical and radiological findings may be non-specific. Distinguishing LIP from miliary TB remains a difficult challenge in HIV-infected children living in high TB prevalence areas. Treatment includes therapy for specific infections, pulmonary clearance techniques, corticosteroids for children with LIP who are hypoxic or who have airway compression from tuberculous nodes and HAART. Children who are taking TB therapy and HAART need adjustments in their drug regimes to minimize drug interactions and ensure efficacy. Preventative strategies include immunization, chemoprophylaxis, and micronutrient supplementation. Early use of HAART may prevent the development of chronic lung disease.

Pulmonary complications of immune reconstitution inflammatory syndromes in HIV-infected patients

RESPIROLOGY, Issue 4 2009
Kristina CROTHERS
ABSTRACT Immune reconstitution inflammatory syndrome (IRIS) describes a paradoxical worsening of clinical status related to recovery of the immune system, as can occur after the initiation of highly active antiretroviral therapy (HAART) in HIV-infected patients. Most commonly, IRIS results from opportunistic infections that can unmask or develop paradoxical worsening following HAART. Cancers, autoimmune conditions and sarcoidosis have also been associated with IRIS. Pulmonary complications may be frequently encountered. This article reviews the types and clinical presentation of IRIS, with a focus on the pulmonary manifestations. Management and outcome of IRIS are considered. [source]

JC virus persistence following progressive multifocal leukoencephalopathy in multiple sclerosis patients treated with natalizumab,

ANNALS OF NEUROLOGY, Issue 3 2010
Caroline F. Ryschkewitsch MT
JC virus (JCV) DNA in the cerebrospinal fluid (CSF) provides the laboratory confirmatory diagnosis of progressive multifocal leukoencephalopathy (PML) in patients whose clinical symptoms and magnetic resonance imaging findings are consistent with PML. The Laboratory of Molecular Medicine and Neuroscience (LMMN), National Institute of Neurological Disorders and Stroke (NINDS), National Institutes of Health (NIH), made the confirmatory laboratory diagnosis in 35 multiple sclerosis (MS) patients treated with natalizumab. Thirteen patients had 3 or more CSF samples taken from weeks to months following PML diagnosis. Seven of the 13 patients demonstrated persistence of JCV DNA in the CSF even though all patients experienced immune reconstitution inflammatory syndrome (IRIS), 11 patients had plasma exchange, and 2 had immunoabsorption. Specific anti-JCV antibody was measured in plasma/sera samples from 25 of the 35 patients. Most of the samples showed moderate to high or rising antibody levels from the time of PML diagnosis. However, plasma from 1 patient at or near the time of PML diagnosis had a titer considered seronegative and 2 other plasma samples from patients had titers considered at baseline for seropositivity. In several PML cases, viral persistence and neurological deficits have continued for several years, indicating that once initiated, JCV infection may not entirely clear, even with IRIS.
