Sequential occurrence of Graves' disease and immune thrombocytopenic purpura as manifestations of immune reconstitution inflammatory syndrome in an HIV-infected patient.

Immune reconstitution inflammatory syndrome (IRIS) in HIV-infected patients after initiating antiretroviral therapy usually involves worsening manifestations of overt infectious disease. Here, we describe a sporadic case of a late-diagnosed HIV-positive man who developed Graves' disease as the first noninfectious IRIS followed by immune thrombocytopenic purpura as the second noninfectious IRIS.

Nerve abscess in Hansen's disease as part of immune reconstitution inflammatory syndrome: a case report.

Immune reconstitution inflammatory syndrome is an inflammatory reaction in HIV-infected patients after initiation of antiretroviral therapy resulting from restored immunity to specific infectious or non-infectious antigens. A 36-year-old male patient on highly active antiretroviral therapy of six months duration, presented with reddish, tender lesions over medial aspect of arm and a single, anaesthetic patch. Tender fluctuant swellings were seen on the medial aspect of left forearm. A few of them had ruptured spontaneously discharging pus. A skin biopsy from the anaesthetic patch showed caseating epitheloid granulomas. A diagnosis of Hansen's disease borderline tuberculoid in type 1 reversal reaction, with formation of nerve abscess due to Immune Reconstitution Inflammatory Syndrome was made. The patient was started on multibacillary multidrug therapy as per WHO guidelines and highly active antiretroviral therapy was continued.

Rates of Serious Infections in HIV-Infected Patients Receiving Tumor Necrosis Factor Inhibitor Therapy for Concomitant Autoimmune Diseases.

OBJECTIVE: To estimate the incidence of serious infections in patients with HIV infection and autoimmune disease who were treated with tumor necrosis factor (TNF) inhibitors, and to compare these rates by stratified viral load levels. METHODS: Using a unified search strategy, 4 centers identified HIV-infected patients exposed to TNF inhibitors. Patient characteristics and infection data were assessed via chart review in all patients who were ≥18 years old and who received TNF inhibitor therapy after HIV diagnosis, between January 1999 and March 2015. RESULTS: We studied 23 patients with 26 uses of TNF inhibitor therapy (86.7 person-years of followup). Two (8.7%) experienced at least 1 serious infection episode, for an overall incidence rate of 2.55 per 100 patient-years (95% confidence interval [95% CI] 0.28-9.23). The incidence rate per 100 patient-years was 3.28 (95% CI 0.04-18.26) among patients with a viral load >500 copies/ml at therapy initiation and 2.09 (0.03-11.65) among patients with a viral load ≤500 copies/ml. CONCLUSION: This study suggests that the rate of serious infections in patients with HIV infection under active care who have received treatment with TNF inhibitors may be comparable to the rates observed in registry databases.

Tuberculoid leprosy and cytomegalovirus retinitis as immune restoration disease in a patient with AIDS.

Here we report a unique case of tuberculoid leprosy and cytomegalovirus retinitis in a 27-year-old female patient with AIDS, suggestive of highly active antiretroviral therapy (HAART)-induced immune restoration disease. After initiation of HAART, the patient presented with decreased visual acuity, hypoesthetic patch with local nerve thickening, and an increase in her CD4+ T cell count. On further investigations cytomegalovirus retinitis and tuberculoid leprosy were confirmed. To our knowledge no case with such a co-existence has previously been reported.

Unmasking tuberculosis in the era of antiretroviral treatment.

Tuberculosis (TB) can develop soon after antiretroviral treatment initiation, as the result of restoration of the anti-TB specific immune response. This form of the disease is often defined as "unmasked TB", and it represents a major challenge for severely immune-suppressed HIV-infected subjects initiating treatment. Emergence of previously unrecognised TB disease occurs frequently in countries where TB/HIV co-infection is common, and where antiretroviral treatment has become increasingly accessible. The challenges posed by unmasked TB, such as its high incidence, the lack of reliable diagnostic tools and the uncertainties on its optimal management, may hamper our ability to face the TB/HIV epidemic. Therefore, unmasked TB appears a major threat to global health and poses additional barriers to successful HIV/AIDS care and treatment programmes. This review focuses on the epidemiology, immunopathogenesis and clinical manifestations of unmasked TB, and provides evidence-based recommendations for management and care of the disease.

Immune reconstitution inflammatory syndrome in leprosy.

Immune reconstitution inflammatory syndrome (IRIS) is a paradoxical deterioration in the clinical status of a patient infected with human immunodeficiency virus (HIV) on highly active antiretroviral treatment (HAART). The immune suppression caused by the virus can initially suppress the clinical manifestations of leprosy which can then be unmasked after treatment with HAART or an inflammatory reaction can occur in the initial months of therapy, resulting from dysregulated recovery of immunity to specific antigens. Both these conditions are identified as IRIS in leprosy. Though this syndrome is a widely recognized entity presently, there is still a lack of universally acceptable diagnostic criteria for the condition. The first case published case of leprosy- associated immune reconstitution disease was reported in 2003 and about 47 confirmed cases of IRIS in leprosy have been reported since then, mostly from Brazil and India. Anti-inflammatory drugs and steroids are the drugs of choice in inflammatory episodes with continuation of antiretroviral therapy. With increasing affordability of antiretroviral therapy, clinicians will put more and more number of human immunodeficiency virus infected patients on therapy and hence an increase in the incidence of IRIS is expected. Therefore, it is important to understand all facets of this syndrome which is becoming more prevalent with each passing day.

Type 2 lepra reaction with HIV1 co-infection: a case report with interesting management implications.

A patient co-infected with leprosy and Human Immunodeficiency Virus (HIV)-type 1 who developed type 2 lepra reaction in the absence of antiretroviral therapy is presented. The reaction responded only after initiating anti retroviral therapy (ART) despite normal CD4+ counts. The present report suggests that type 2 reactions in leprosy and HIV co-infected patients may not always be the typical manifestation of immune reconstitution inflammatory syndrome (IRIS) and stresses the importance of considering concomitant HIV infection in refractory lepra reactions. Extensive research is required into the manifestations of HIV in leprosy patients.

Drug-induced uveitis in aids patients: two case reports.

Patients with acquired immunodeficiency syndrome (AIDS) can develop severe uveitis. Although infectious and autoimmune causes must always be considered, drug induced uveitis is also an important etiology. Herein, we present two case reports illustrating the classical presentation of rifabutin and cidofovir induced uveitis. The first case was a 33 year old woman with AIDS treated with anti-protease and anti-tuberculosis drugs (including rifabutin). She presented with a red painful right eye. There was a strong anterior segment inflammation with fibrinous exudates and a dense vitritis. Rifabutin was stopped and topical steroids and mydriatics were given. Intraocular inflammation and symptoms rapidly resolved. The second patient was a 36 year old woman who presented with a painful decrease of vision in her left eye. She was followed for bilateral CMV retinitis in the setting of AIDS and had recently received 2 systemic injections of cidofovir. Anterior segment inflammation with posterior synechiae in both eyes and folds of Descemet membrane in the left eye were noted. Intraocular pressure was 0 mmHg in the left eye and 10 mmHg in the right eye. Fundus examination disclosed CMV retinitis scars in the right eye and choroidal folds in the macula of the left eye. Cidofovir was discontinued and topical steroids and mydriatics started. Progressively the inflammation decreased and the intraocular pressure returned to normal levels. In conclusion, rifabutin and cidofovir are classical examples of drug induced uveitis with distinct characteristic clinical presentation. Recognition of those entities in AIDS patients can avoid useless and potentially invasive interventions in those fragile people.
