Abstract
Prior to the introduction of antiretroviral therapy, the concomitant occurrence of sarcoidosis and human immunodeficiency virus (HIV) was extremely rare. Today, an increased prevalence of sarcoidosis as a result of immune reconstitution syndrome (IRIS) is observed in HIV patients. A 37-year-old male patient that was co-infected with HIV and hepatitis C had a 6‑month history of gradually progressive asymptomatic periorbital erythematous plaques and papules. Routine clinical examinations were normal. Skin punch biopsy taken from the upper portion of the right cheek showed several non-caseating dermal granulomas with multinucleated giant cells, enabling unequivocal histological diagnosis. Based on the clinical picture and histological findings, the patient was diagnosed with cutaneous sarcoidosis. This case study underlines the change in possible rheumatological and dermatological comorbities in HIV-positive patients treated with highly active antiretroviral therapy. Therefore, physicians treating HIV infections should be familiar with the definition of IRIS.

Abstract
Immune checkpoint inhibitors (ICIs) are a newly developed component of cancer care that expands the treatment possibilities for patients. Their use has been associated with several immune-related adverse events, including ICI-induced sarcoidosis-like reactions. This article reviews the data concerning ICI-induced sarcoidosis-like reactions currently available in the medical literature. These reactions have been reported in three classes of ICIs: anti-cytotoxic T-lymphocyte associated protein 4 antibodies, programmed death 1 inhibitors and programmed death ligand 1 inhibitors. These reactions are indistinguishable from sarcoidosis with a similar histology, pattern of organ involvement, and pattern of clinical manifestations. The most common locations to observe granulomatous inflammation from these reactions is in intrathoracic locations (the lung and/or mediastinal lymph nodes) and the skin. The median time between initiation of an ICI and the development of a sarcoidosis-like reaction averaged 14 weeks. Clinicians have opted to use corticosteroids and/or discontinue the ICI, or take no action when these reactions have developed. Regardless of whether the clinician performed an intervention or not, these reactions have uniformly improved or resolved after ICI-treatment, which provides additional temporal evidence supporting the presence of a sarcoidosis-like reaction as opposed to sarcoidosis. There is even evidence that the development of an ICI-induced sarcoidosis-like reaction suggests that the ICI is effective as an anti-tumor agent and should be continued. As is the case for sarcoidosis, sarcoidosis-like reactions do not mandate antisarcoidosis therapy, especially if the condition is asymptomatic. When treatment of sarcoidosis-like reaction is required, it may be prudent to continue ICI therapy and add antisarcoidosis therapy because standard antisarcoidosis regimens seem to be effective. Further research into the mechanisms involved in the development of ICI-induced sarcoidosis-like reactions may give insights into the immunopathogenesis of sarcoidosis.

Abstract
A drug-induced sarcoidosis-like reaction (DISR) is a systemic granulomatous reaction that is indistinguishable from sarcoidosis and occurs in a temporal relationship with initiation of an offending drug. DISRs typically improve or resolve after withdrawal of the offending drug. Four common categories of drugs that have been associated with the development of a DISR are immune checkpoint inhibitors, highly active antiretroviral therapy, interferons, and tumor necrosis factor-α antagonists. Similar to sarcoidosis, DISRs do not necessarily require treatment because they may cause no significant symptoms, quality of life impairment, or organ dysfunction. When treatment of a DISR is required, standard antisarcoidosis regimens seem to be effective. Because a DISR tends to improve or resolve when the offending drug is discontinued, this is another effective treatment for a DISR. However, the offending drug need not be discontinued if it is useful, and antigranulomatous therapy can be added. In some situations, the development of a DISR may suggest a beneficial effect of the inducing drug. Understanding the mechanisms leading to DISRs may yield important insights into the immunopathogenesis of sarcoidosis.

Abstract
In HIV-infected individuals, paradoxical reactions after the initiation of antiretroviral therapy (ART) are associated with a variety of underlying infections and have been called the immune reconstitution inflammatory syndrome (IRIS). In cases of IRIS associated with tuberculosis (TB), two distinct patterns of disease are recognized: (i) the progression of subclinical TB to clinical disease after the initiation of ART, referred to as unmasking, and (ii) the progression or appearance of new clinical and/or radiographic disease in patients with previously recognized TB after the initiation of ART, the classic or "paradoxical" TB-IRIS. IRIS can potentially occur in all granulomatous diseases, not just infectious ones. All granulomatous diseases are thought to result from interplay of inflammatory cells and mediators. One of the inflammatory cells thought to be integral to the development of the granuloma is the CD4 T lymphocyte. Therefore, HIV-infected patients with noninfectious granulomatous diseases such as sarcoidosis may also develop IRIS reactions. Here, we describe IRIS in HIV-infected patients with TB and sarcoidosis and review the basic clinical and immunological aspects of these phenomena.

Abstract
To describe the clinical manifestations, treatments, prognosis, and prevalence of autoimmune diseases (ADs) in human immunodeficiency virus (HIV)-infected patients.All HIV-infected patients managed in the Infectious Diseases Department of the Lyon University Hospitals, France, between January 2003 and December 2013 and presenting an AD were retrospectively included.Thirty-six ADs were found among 5186 HIV-infected patients which represents a prevalence of 0.69% including immune thrombocytopenic purpura (n = 15), inflammatory myositis (IM) (n = 4), sarcoidosis (n = 4), Guillain-Barré syndrome (GBS) (n = 4), myasthenia gravis (n = 2), Graves' disease (n = 2), and 1 case of each following conditions: systemic lupus erythematosus, rheumatoid arthritis, autoimmune hepatitis, Hashimoto thyroiditis and autoimmune hemolytic anemia. One patient presented 2 ADs. Thirty patients were known to be HIV-infected when they developed an AD. The AD preceded HIV infection in 2 patients. GBS and HIV infection were diagnosed simultaneously in 3 cases. At AD diagnosis, CD4 T lymphocytes count were higher than 350/mm in 63% of patients, between 200 and 350/mm in 19% and less than 200/mm in 19%. Twenty patients benefited from immunosuppressant treatments, with a good tolerance.ADs during HIV infection are uncommon in this large French cohort. Immune thrombocytopenic purpura, sarcoidosis, IM, and GBS appear to be more frequent than in the general population. Immunosuppressant treatments seem to be effective and well tolerated.

Abstract
BACKGROUND Visceral leishmaniasis is not normally expressed in skin. Herein, we describe the case of an HIV-positive patient who developed two unusual skin manifestations during an episode of visceral leishmaniasis. PATIENTS AND METHODS A 48-year-old female patient consulted initially for infiltrated purpura of all four limbs. Skin biopsy revealed leukocytoclastic vasculitis with Leishman-Donovan bodies. Laboratory tests showed medullary, splenic, gastric and colic involvement, suggesting systemic disease, and enabling visceral leishmaniasis to be diagnosed. Two years later, despite prolonged treatment, the patient presented maculopapular exanthema, and histology revealed persistent Leishman-Donovan bodies. DISCUSSION We report herein an association of two rare skin manifestations in an HIV-positive patient with visceral leishmaniasis: infiltrated purpura and maculopapular exanthema. However, the underlying mechanisms remain hypothetical. The initial leukocytoclastic exanthema could be secondary to either polyclonal hypergammaglobulinaemia or to IgA deposits, or possibly to mechanical impairment of blood vessels by the actual parasite. The maculopapular exanthema occurring later raised the possibility of post-Kala-Azar leishmaniasis due to blood-borne dissemination in an anergic subject or perhaps even immune reconstitution inflammatory syndrome.

Abstract
Background: People with human immunodeficiency virus may experience an immune restoration syndrome during the lymphocyte recovery period following effective highly active antiretroviral therapy. In this syndrome, antigens that previously were ignored by the immune system now induce an exaggerated response with obvious clinical effects. Most cases have been associated with infectious agents such as cytomegalovirus or mycobacterium avium intracellulare. However, the sudden onset of sarcoidal granulomatous reactions have also been described in this setting. Objective: We report a 66-year-old HIV-positive man who presented with exacerbation of multiple foreign body granulomas decades after the original injuries. The presentation coincided with a significant rise in CD4 count after beginning highly active antiretroviral therapy. Conclusion: We propose that this case demonstrates another manifestation of the immune restoration syndrome and postulate that an uncontrolled Th1 response is the causative mechanism.

Abstract
Exacerbations of sarcoidosis are common. In particular, exacerbations of pulmonary sarcoidosis are reported in more than one-third of patients. Despite their frequent occurrence, there is little medical evidence concerning the definition, diagnosis, and treatment of pulmonary exacerbations of sarcoidosis. In this article, we propose a definition of acute pulmonary exacerbations of sarcoidosis (APES). We review the meager medical literature concerning the risk factors, diagnosis, and treatment of this condition. Given the limited information concerning APES, we acknowledge that this article is not a definitive resource but, rather, a position paper that will encourage greater consideration of the pathogenesis, diagnostic challenges, and treatment approaches to this condition. We believe that further focus on APES will improve the quality of care of patients with pulmonary sarcoidosis.

Abstract
A spectrum of noninfectious, nonmalignant lymphocytic infiltrative disorders, including nonspecific interstitial pneumonitis and lymphocytic interstitial pneumonitis, was frequently described in HIV-infected adults in the precombination antiretroviral therapy (ART) era. With the advent of ART, these conditions are less commonly encountered when caring for HIV-infected adults, possibly as a consequence of the effects of HIV treatment on pulmonary immunology. By contrast, reports of sarcoidosis among HIV-infected persons were uncommon in the pre-ART era, but sarcoidosis is increasingly recognized since the introduction of ART and may represent an immune reconstitution phenomenon. Other causes of interstitial pneumonitis are infrequently encountered among HIV-infected persons.

Abstract
Immune reconstitution inflammatory syndrome (IRIS) in HIV-infected subjects initiating antiretroviral therapy most commonly involves new or worsening manifestations of previously subclinical or overt infectious diseases. Reports of non-infectious IRIS are much less common but represent important diagnostic and treatment challenges. We report on a 34-year-old HIV-infected male patient with no history of gout who developed acute gouty arthritis in a single joint one month after initiating highly active antiretroviral therapy.

Abstract
Antiretroviral therapy (ART) initiation in HIV-infected patients leads to recovery of CD4+T cell numbers and restoration of protective immune responses against a wide variety of pathogens, resulting in reduction in the frequency of opportunistic infections and prolonged survival. However, in a subset of patients, dysregulated immune response after initiation of ART leads to the phenomenon of immune reconstitution inflammatory syndrome (IRIS). The hallmark of the syndrome is paradoxical worsening of an existing infection or disease process or appearance of a new infection/disease process soon after initiation of therapy. The overall incidence of IRIS is unknown, but is dependent on the population studied and the burden of underlying opportunistic infections. The immunopathogenesis of the syndrome is unclear and appears to be result of unbalanced reconstitution of effector and regulatory T-cells, leading to exuberant inflammatory response in patients receiving ART. Biomarkers, including interferon-γ (INF-γ), tumour necrosis factor-α (TNF-α), C-reactive protein (CRP) and inter leukin (IL)-2, 6 and 7, are subject of intense investigation at present. The commonest forms of IRIS are associated with mycobacterial infections, fungi and herpes viruses. Majority of patients with IRIS have a self-limiting disease course. ART is usually continued and treatment for the associated condition optimized. The overall mortality associated with IRIS is low; however, patients with central nervous system involvement with raised intracranial pressures in cryptococcal and tubercular meningitis, and respiratory failure due to acute respiratory distress syndrome (ARDS) have poor prognosis and require aggressive management including corticosteroids. Paradigm shifts in management of HIV with earlier initiation of ART is expected to decrease the burden of IRIS in developed countries; however, with enhanced rollout of ART in recent years and the enormous burden of opportunistic infections in developing countries like India, IRIS is likely to remain an area of major concern.

Abstract
PURPOSE OF REVIEW Immune reconstitution inflammatory syndrome (IRIS) is a common occurrence in HIV patients starting antiretroviral therapy (ART), and pulmonary involvement is an important feature of tuberculosis-IRIS and pneumocystis-IRIS. Pulmonologists need an awareness of the timing, presentation and treatment of pulmonary IRIS. RECENT FINDINGS Case definitions for tuberculosis-IRIS and cryptococcal-IRIS have been published by the International Network for the Study of HIV-associated IRIS (INSHI). A number of studies have addressed validation of clinical case definitions and the optimal time to commence ART after diagnosis of an opportunistic infection in HIV patients. The pathogenesis of IRIS is being assessed at a molecular level, increasing our understanding of mechanisms and possible targets for future preventive and therapeutic strategies. SUMMARY Tuberculosis-IRIS, nontuberculosis mycobacterial-IRIS and pneumocystis-IRIS occur within days to weeks of starting ART, causing substantial morbidity, but low mortality. Cryptococcal-IRIS usually occurs later in the course of ART, and may be associated with appreciable mortality. Early recognition of unmasking and paradoxical IRIS affecting the lung allows timely initiation of antimicrobial and/or immunomodulatory therapies.

Abstract
Microbes are increasingly being implicated in autoimmune disease. This calls for a re-evaluation of how these chronic inflammatory illnesses are routinely treated. The standard of care for autoimmune disease remains the use of medications that slow the immune response, while treatments aimed at eradicating microbes seek the exact opposite-stimulation of the innate immune response. Immunostimulation is complicated by a cascade of sequelae, including exacerbated inflammation, which occurs in response to microbial death. Over the past 8 years, we have collaborated with American and international clinical professionals to research a model-based treatment for inflammatory disease. This intervention, designed to stimulate the innate immune response, has required a reevaluation of disease progression and amelioration. Paramount is the inherent conflict between palliation and microbicidal efficacy. Increased microbicidal activity was experienced as immunopathology-a temporary worsening of symptoms. Further studies are needed, but they will require careful planning to manage this immunopathology.

Abstract
Coexistence of HIV, pulmonary sarcoidosis, and human T-cell lymphotrophic viruses (HTLV) I/II has not been well reported and studied. Although the exact etiology of sarcoidosis is unknown, immunologic abnormalities have been the focus of human immunodeficiency virus (HIV)-related sarcoidosis and it is thought to be a manifestation of immune reconstitution inflammatory syndrome. We report the case of an African American woman with HIV and HTLV I/II coinfection who developed pulmonary sarcoidosis several months after the initiation of antiretroviral therapy. Despite the fact that most common etiologies of pulmonary nodules in HIV patients include mycobacterial and fungal infections, sarcoidosis should be considered in differential diagnosis. This disease may continuously rise due to the increasing number of people who are receiving antiretroviral therapy, leading to an improved immune system.

Abstract
The immune reconstitution syndrome (IRS) is an increasingly recognized disease concept and is observed with a broad-spectrum of immunosuppressive therapy-related opportunistic infectious diseases and severe drug eruptions complicated by viral reactivations. Clinical illness consistent with IRS includes tuberculosis, herpes zoster, herpes simples, cytomegalovirus infections and sarcoidosis: thus, the manifestations of this syndrome and diverse and depend on the tissue burden of the preexisting infectious agents during the immunosuppressive state, the nature of the immune system being restored, and underlying diseases of the hosts. Although IRS has originally been reported to occur in the setting of HIV infection, it has become clear that the development of IRS can also be in HIV-negative hosts receiving immunosuppressive agents, such as prednisolone and tumor necrosis factor α inhibitors, upon their reduction and withdrawal. Drug-induced hypersensitivity syndrome, a life-threatening multiorgan system reaction, is another manifestation of the newly observed IRS. Clinical recognition of the IRS is especially important in improving the outcome for diseases with an otherwise life-threatening progenosis. Clinicians should be aware of the implications of IRS and recognize that relieving the symptoms and signs of immune recovery by anti-inflammatory therapies needs to be balanced with anti-microbial therapies aiming at reducing the amplitude and duration of tissue burden of preexisting microbes.

Abstract
The histopathological assessment of cutaneous lesions is critical to the definitive diagnosis of many human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome-associated dermatoses, infections and tumours. Dermatopathological challenges stem mainly from the altered histopathological profile of established cutaneous entities compared with that in the HIV-unaffected population, the emergence of new diseases and the impact of therapeutic modalities on cutaneous lesions. This review focuses on some of these diagnostic dilemmas, with emphasis on the following challenges: (i) infective diagnostic pitfalls; (ii) itchy papular skin lesions; (iii) co-lesional comorbid diseases; (iv) drug-induced disease alterations; and (v) neoplastic and pseudoneoplastic proliferations. The drug-induced alterations include highly active antiretroviral therapy-associated disease modifications.

Abstract
An HIV positive male from Brazil, living in Italy since 1989, developed a single non-itching, papulo-erythematous infiltrative lesion on the face after 2 months from the beginning of HAART. A diagnosis of leprosy was made, suggesting that the immunodeficiency masked the disease, until the skin manifestation became evident with immune-recovery.

Abstract
The use of antiretroviral therapy (ART) to treat HIV infection, by restoring CD4+ cell count and immune function, is associated with significant reductions in morbidity and mortality. Soon after ART initiation, there is a rapid phase of restoration of pathogen-specific immunity. In certain patients, this results in inflammatory responses that may result in clinical deterioration known as 'the immune reconstitution inflammatory syndrome' (IRIS). IRIS may be targeted at viable infective antigens, dead or dying infective antigens, host antigens, tumour antigens and other antigens, giving rise to a heterogeneous range of clinical manifestations. The commonest forms of IRIS are associated with mycobacterial infections, fungi and herpes viruses. In most patients, ART should be continued and treatment for the associated condition optimized, and there is anecdotal evidence for the use of corticosteroids in patients who are severely affected. In this review, we discuss research relating to pathogenesis, the range of clinical manifestations, treatment options and prevention issues.

Abstract
Background: Dermatologic conditions are often an early clue to human immunodeficiency virus (HIV) infection. As the disease progresses and the host immunity fails, patients may develop a number of skin conditions. At this point, they have a dominant T helper 2 immunologic response. After the initiation of antiretroviral therapy, the T helper 1 response is restored, and some skin problems, paradoxically, make their appearance then. Conclusion: Herpes zoster, mucocutaneous herpes, eosinophilic folliculitis, and mycobacterial infections have been known to occur at this stage. This may be because immune restoration of a host's immunity causes recognition of silent or latent infection and results in development of the condition. We report five cases that were seen at our center during a 2-year period.

Abstract
HIV-specific T-lymphocyte responses that underlie IRIS are incomplete and largely remain hypothetical. Of the several mechanisms presented by the host to control host immunological damage, Treg cells are believed to play a critical role. Using the available experimental evidence, it is proposed that enormous synthesis of conventional FoxP3- Th cells (responsive) often renders subjects inherently vulnerable to IRIS, whereas that of natural FoxP3+ Treg cell synthesis predominate among subjects that may not progress to IRIS. We also propose that IRIS non-developers generate precursor T-cells with a high avidity to generate CD4+CD25+FoxP3+ Tregs whereas IRIS developers generate T-cells of intermediate avidity yielding Th0 cells and effector T-cells to mediate the generation of proinflammatory cytokines in response to cell-signaling factors (IL-2, IL-6 etc.). Researchers have shown that IL-10 Tregs (along with TGF-β, a known anti-inflammatory cytokine) limit immune responses against microbial antigens in addition to effectively controlling HIV replication, the prime objective of HAART. Although certain technical limitations are described herein, we advocate measures to test the role of Tregs in IRIS.

Abstract
Gut immune components are severely compromised among persons with AIDS, which allows increased translocation of bacterial lipopolysaccharides (LPS) into the systemic circulation. These microbial LPS are reportedly increased in chronically HIV-infected individuals and findings have correlated convincingly with measures of immune activation. Immune reconstitution inflammatory syndrome (IRIS) is an adverse consequence of the restoration of pathogen-specific immune responses in a subset of HIV-infected subjects with underlying latent infections during the initial months of highly active antiretroviral treatment (HAART). Whether IRIS is the result of a response to a high antigen burden, an excessive response by the recovering immune system, exacerbated production of pro-inflammatory cytokines or a lack of immune regulation due to inability to produce regulatory cytokines remains to be determined. We theorize that those who develop IRIS have a high burden of proinflammatory cytokines produced also in response to systemic bacterial LPS that nonspecifically act on latent mycobacterial antigens. We also hypothesize that subjects that do not develop IRIS could have developed either tolerance (anergy) to persistent LPS/tubercle antigens or could have normal FOXP3+ gene and that those with defective FOXP3+ gene or those with enormous plasma LPS could be vulnerable to IRIS. The measure of microbial LPS, anti-LPS antibodies and nonspecific plasma cytokines in subjects on HAART shall predict the role of these components in IRIS.

Abstract
We describe a 41-year-old human immunodeficiency virus-infected woman with a previous history of intravenous drug abuse, who developed multiple linear nodules following the superficial veins on both arms. Histopathological examination disclosed a dermal histiocytic inflammatory reaction with sarcoid-like granuloma formation occasionally showing an intracytoplasmic refractile material in the histiocytic cells. Nodular lesions developed progressively after starting on highly active antiretroviral therapy (HAART) which increased her CD4 cell count and suppressed her viral load. The appearance of latent inflammatory or autoimmune disease following HAART is a well-recognized phenomenon. We consider that this peculiar 'progressive supravenous granulomatous nodular eruption' should be included within the spectrum of the so-called immune reconstitution inflammatory syndrome.

Abstract
The immune reconstitution inflammatory syndrome (IRIS) in HIV-infected patients initiating antiretroviral therapy (ART) results from restored immunity to specific infectious or non-infectious antigens. A paradoxical clinical worsening of a known condition or the appearance of a new condition after initiating therapy characterizes the syndrome. Potential mechanisms for the syndrome include a partial recovery of the immune system or exuberant host immunological responses to antigenic stimuli. The overall incidence of IRIS is unknown, but is dependent on the population studied and its underlying opportunistic infectious burden. The infectious pathogens most frequently implicated in the syndrome are mycobacteria, varicella zoster, herpesviruses, and cytomegalovirus (CMV). No single treatment option exists and depends on the underlying infectious agent and its clinical presentation. Prospective cohort studies addressing the optimal screening and treatment of opportunistic infections in patients eligible for ART are currently being conducted. These studies will provide evidence for the development of treatment guidelines in order to reduce the burden of IRIS. We review the available literature on the pathogenesis and epidemiology of IRIS, and present treatment options for the more common infectious manifestations of this diverse syndrome and for manifestations associated with a high morbidity.

Abstract
The immunopathogenesis of sarcoidosis has been difficult to charaterize given the heterogeneity of disease, the elusiveness of the causative antigen, and the lack of an adequate animal model. However, by examining well-defined clinical cohorts, the interplay between genetic predisposition and immunologic response has been increasingly informative. Technological advances in cellular analysis have allowed researchers to characterize the immune responses important in the maintenance of granulomatous inflammation. Finally, "new" clinical observations such as granuloma responsiveness to targeted biological therapies, sarcoid developing during immune restoration, and the relationship between sarcoidosis and Hepatitis C will provide future insight to the immunopathogenesis of sarcoidosis.

Abstract
In the era of highly active antiretroviral therapy (HAART), immune reconstitution inflammatory syndrome (IRIS) has come to present a significant clinical challenge. Following the recovery of memory T cells, latent infections may lead to clinical and laboratory deterioration despite immunological and virological reconvalescence. However, many other forms of complications after induction of HAART, which are not entirely understood, must be included in the entity of IRIS. Here we report a case of a patient complaining of respiratory distress and fever 10 days after initiating HAART. Radiologically and clinically, his findings mimicked Pneumocystis jiroveci pneumonia. However, no infectious agent could be detected, and bronchoalveolary lavage showed a high cell count (90% lymphocytes and 4% eosinophils) consistent with interstitial pneumonitis. He improved dramatically after treatment with oral steroids.

Abstract
Highly active antiretroviral therapy (HAART)-treated human immunodeficiency virus (HIV)-positive patients can develop granulomatous lesions within the first few weeks of initiating therapy. This immune syndrome, called immune restoration inflammatory syndrome (IRIS), can induce sarcoid-like lesions in tissues. The pathogenesis of these granulomas is currently unknown because no pathogen has been identified to date in the lesions using morphological and/or microbiological approaches. However, the role of certain microbes, such as Mycobacterium tuberculosis, is still debated. The aim of this study was to look for the presence of M. tuberculosis in sarcoid-like lesions occurring in 14 AIDS patients treated with HAART. We used the PCR DNA amplification method in granulomas microdissected from sections stained by hematoxylin-eosin from formalin-fixed, paraffin-embedded specimens. Results were compared to those obtained from microdissected tuberculosis (TB) granulomas (15 patients) and from microdissected sarcoidosis granulomas (12 patients). M. tuberculosis DNA was undetectable from the microdissected sarcoid-like granulomas, whereas DNA from M. tuberculosis was isolated in all the microdissected TB granulomas and was absent in the microdissected sarcoidosis granulomas. Taken together, these data showed that M. tuberculosis DNA is not associated with the presence of sarcoid-like lesions occurring in HIV-positive patients treated with HAART.

Abstract
The immune reconstitution inflammatory syndrome (IRIS) represents a diverse range of immunopathologic reactions resulting in clinical deterioration that may occur as immune function is partially restored in HIV-infected patients receiving highly active antiretroviral therapy. Approximately half of IRIS events are dermatologic, and dermatologic IRIS is described in relation to a wide range of conditions, the commonest being herpes zoster and herpes simplex. Most cases of IRIS result in mild and moderate symptoms, but non-dermatologic manifestations related to IRIS have resulted in death. This article covers certain general issues related to IRIS and then focuses on the spectrum of dermatologic manifestations.

Abstract
OBJECTIVE To describe the impact of the introduction of highly active antiretroviral therapy (HAART) on the nature and frequency of rheumatic complications in human immunodeficiency virus (HIV)-infected patients. METHODS Case report and systematic review of a newly described syndrome of rheumatic immune reconstitution syndrome and prospective longitudinal cohort study analyzing the frequency and nature of rheumatic complications in the setting of HIV infection from 1989 through 2000. RESULTS A newly described syndrome of either the de novo appearance or the exacerbation of clinically occult autoimmunity following immune reconstitution from HAART is described. Including the present case report, 32 cases have been individually described with sarcoidosis and autoimmune thyroid disease being most common with arthritis and various forms of connective tissue disease making up the rest. The mean onset to their appearance following HAART was nearly 9 months and most resolved with little or no therapy. In addition, a longitudinal analysis of 395 HIV-infected patients from 1989 to 2000 designed to detect the appearance of rheumatic complications has revealed a dramatic decline in certain problems such as reactive arthritis, psoriatic arthritis, and various forms of connective tissue disease. New rheumatic complications possibly due to the effects of longer survival and metabolic derangements associated with this form of therapy are now being described and may become more formidable problems in this population in the future. CONCLUSIONS HAART has had a profound beneficial effect on survival in HIV-infected patients but has also contributed to both an altered frequency and a different nature of rheumatic complications now being observed in this population. Rheumatologists need to be aware of these changes to provide optimal diagnosis and treatment for this group.

Abstract
Systemic lupus erythematosus (SLE) and infection with human immunodeficiency virus are rarely seen in the same patient. We describe a case of a 32-year-old lady, who was diagnosed with systemic lupus erythematosus (anti-dsDNA antibody positive) and was initially serologically negative for human immunodeficiency virus (HIV) infection. Following three cycles of IV cyclophosphamide, she was subsequently found to be infected with HIV, with marked depletion of peripheral CD4-positive T lymphocytes. While her SLE remained completely inactive, the course of HIV was rapidly progressive, suggesting that retroviral replication may have been enhanced by the underlying immunomodulation caused by cyclophosphamide and also by SLE per se.

Relapsing polychondritis is a rare autoimmune disease characterized by inflammation and degeneration of cartilaginous tissue. We describe the first reported cases of relapsing polychondritis in patients with human immunodeficiency virus (HIV) and no associated connective tissue diseases. The relationship between autoimmune and HIV diseases is complex and unclear. Treatment of HIV disease with antiretroviral therapy and subsequent immune restoration may lead to the development of autoimmune diseases in genetically susceptible individuals.

Abstract
Members of the Mycobacterium avium complex (MAC) are important environmental pathogens that are implicated in several chronic, idiopathic diseases. Diagnosis of MAC-based diseases is compromised by the need to cultivate these fastidious and slowly growing organisms in order to identify which mycobacterial species are present. Detection is particularly difficult when MAC is intracellular or embedded within mammalian tissues. We report on the development of culture-independent, in situ hybridization (ISH) assays for the detection of MAC in culture, sputum, and tissue. This assay includes a highly reliable technique for the permeabilization of mycobacterial cells within culture and tissues. We describe a set of rRNA-based oligonucleotide probes that specifically detect either M. intracellulare, the two M. avium subspecies associated with human disease, or all members of MAC. The results call into question the validity of ISH results derived by the use of other gene loci, such as IS900.

Abstract
Effective highly active antiretroviral therapy (HAART) has increased survival in patients infected with the human immunodeficiency virus (HIV). However, HAART is not without toxicities. Cutaneous adverse reactions from antiretroviral agents have become increasingly important to recognize as the population of patients surviving with HIV infection grows. Dermatologists play an important role in managing these cutaneous effects of HAART therapy in HIV patients. This article reviews cutaneous adverse effects from nucleoside reverse transcriptase inhibitors, non-nucleoside reverse transcriptase inhibitors, protease inhibitors, and fusion inhibitors, as well as separately addresses lipodystrophy, and immune reconstitution.

Abstract
Some individuals who initiate highly active antiretroviral therapy (HAART) develop new or worsening opportunistic infections or malignancies despite improvements in surrogate markers of HIV-1 infection. These events of paradoxical clinical worsening, also known as immune reconstitution syndromes (IRS), are increased in individuals with prior opportunistic infections or low CD4+ T-cell nadirs. They are thought to result from reconstitution of the immune system's ability to recognize pathogens or tumor antigens that were previously present, but clinically asymptomatic. There is no consensus regarding the diagnostic criteria or pathogenesis of IRS. Knowledge of their presentation and treatment is largely based on case reports. With the introduction of HAART into resource-limited settings, it is likely that significantly more and distinct forms of IRS will be observed. Prospective studies of the incidence and treatment of IRS in multiple settings are critical to better understand their pathogenesis and optimal management.

Abstract
Tumid lupus erythematosus (LE) is a relatively rare and only recently recognized subset of chronic cutaneous lupus. We report a case occurring in a male with HIV infection whereby his rash was only unmasked by immune restoration following highly active antiretroviral therapy (HAART). The phenomenon of latent inflammatory or autoimmune disease appearing following HAART is now recognized as the "immune restoration syndrome" and tumid LE has not been reported in this setting previously. Fortunately this variant of lupus does not result in scarring and is responsive to anti-malarials, allowing continuation of HAART in this patient.

Abstract
Suppression of HIV replication by highly active antiretroviral therapy (HAART) often restores protective pathogen-specific immune responses, but in some patients the restored immune response is immunopathological and causes disease [immune restoration disease (IRD)]. Infections by mycobacteria, cryptococci, herpesviruses, hepatitis B and C virus, and JC virus are the most common pathogens associated with infectious IRD. Sarcoid IRD and autoimmune IRD occur less commonly. Infectious IRD presenting during the first 3 months of therapy appears to reflect an immune response against an active (often quiescent) infection by opportunistic pathogens whereas late IRD may result from an immune response against the antigens of non-viable pathogens. Data on the immunopathogenesis of IRD is limited but it suggests that immunopathogenic mechanisms are determined by the pathogen. For example, mycobacterial IRD is associated with delayed-type hypersensitivity responses to mycobacterial antigens whereas there is evidence of a CD8 T-cell response in herpesvirus IRD. Furthermore, the association of different cytokine gene polymorphisms with mycobacterial or herpesvirus IRD provides evidence of different pathogenic mechanisms as well as indicating a genetic susceptibility to IRD. Differentiation of IRD from an opportunistic infection is important because IRD indicates a successful, albeit undesirable, effect of HAART. It is also important to differentiate IRD from drug toxicity to avoid unnecessary cessation of HAART. The management of IRD often requires the use of anti-microbial and/or anti-inflammatory therapy. Investigation of strategies to prevent IRD is a priority, particularly in developing countries, and requires the development of risk assessment methods and diagnostic criteria.

Abstract
Summary Immune reconstitution is a well recognized phenomenon associated with the use of highly active antiretroviral therapy (HAART) for HIV infection. After the administration of HAART there is a rise in CD4 T-cell count in the circulation brought about by cessation of HIV replication. This allows the body to respond to antigens that it previously ignored. This manifests itself most commonly as an overt illness to previously ignored pre-existing infections such as Mycobacterium tuberculosis, herpes simplex virus, varicella zoster virus, hepatitis B and C viruses, cytomegalovirus, cryptococcal infection, human papilloma virus and molluscum contagiosum. There are further reports of reactions to sarcoid and tattoo pigment and one previous case reported of a granulomatous reaction to a foreign body. We report another case of a foreign body granuloma reaction, to tribal medicine implanted in tribal marks made in childhood in a Zimbabwean woman. This reaction is part of the immune reconstitution syndrome.

Abstract
The prognosis of patients infected with human immunodeficiency virus (HIV) type 1 has dramatically improved since the advent of potent antiretroviral therapies (ARTs), which have enabled sustained suppression of HIV replication and recovery of CD4 T cell counts. Knowledge of the function of CD4 T cells in immune reconstitution was derived from large clinical studies demonstrating that primary and secondary prophylaxis against infectious agents, such as Pneumocystis jirovecii (Pneumocystis carinii), Mycobacterium avium complex, cytomegalovirus, and other pathogens, can be discontinued safely once CD4 T cell counts have increased beyond pathogen-specific threshold levels (usually >200 CD4 T cells/mm3) for 3-6 months. The downside of immune reconstitution is an inflammatory syndrome occurring days to months after the start of ART, with outcomes ranging from minimal morbidity to fatal progression. This syndrome can be elicited by infectious and noninfectious antigens. Microbiologically, the possible pathogenic pathways involve recognition of antigens associated with ongoing infection or recognition of persisting antigens associated with past (nonreplicating) infection. Specific antimicrobial therapy, nonsteroidal anti-inflammatory drugs, and/or steroids for managing immune reconstitution syndrome should be considered.
