Peer reviewers were asked to review the guideline for accuracy, balance, clarity, and practicality of the recommendations for primary care providers. The Planning Group addressed peer review feedback; any conflicting opinions were resolved by the Committee chairs. Once the guideline is published on the program website: www. Notification of newly published studies will be automated, and the Planning Group will review new data at least every 6 months.
Newly published data that provide support for existing recommendations will be cited in the text, and the studies will be added to the reference list s. If newly published data prompt a revision to recommendations or rationale, the Planning Group will propose appropriate edits and determine whether the changes warrant review and approval by the entire MCCC. If MCCC review is required, a conference call will be convened for that purpose.
The full guideline will be reviewed and updated on the 4th anniversary of original publication to prepare for publication of an updated guideline on or before the 5th anniversary of original publication. IRIS, which is also known as immune restoration disease, refers to a disease- or pathogen-specific inflammatory response that may be triggered after ART initiation in treatment-naive patients, after re-initiation of ART, or after a change to a more effective ART regimen in patients who fail to achieve viral suppression.
It usually presents within the first 4 to 8 weeks after ART initiation but has occurred many weeks later and in sequestered sites, such as bone [McComsey, et al.
For example, IRIS may occur without a significant increase in the absolute CD4 count, suggesting that measurements obtained from the peripheral blood may not reflect the number of CD4 cells present at the site of an opportunistic infection OI [Haddow, et al. Some studies have found a higher incidence of IRIS in patients treated with regimens containing integrase strand transfer inhibitors.
This may be related to the rapid drop in viral load seen in patients treated with these agents [Dutertre, et al. Although understanding of the pathogenesis of IRIS, including the inflammatory role of T-regulatory cells and cytokine imbalances [Shankar, et al.
IRIS may be more severe in patients with a higher burden of an OI organism, suggesting that antigen load may play a role in pathogenesis [Shelburne, et al. Significant heterogeneity between studies was also noted, in part, because of non-standardized diagnostic criteria and difficulty in distinguishing IRIS from the progression of OIs. However, the studies were conducted in the era before early treatment, when ART was more often initiated in patients with low CD4 counts, and, as retrospective studies, are more likely to overestimate the incidence of IRIS.
Data on unmasking IRIS are limited primarily to case reports. IRIS is associated with an increased risk of death, with a reported overall mortality rate of 4. However, mortality rates depend on the associated OI, access to treatment, diagnostic criteria, degree of immunosuppression, and geography.

EClinicalMedicine ; Clinicians should strongly recommend that patients being treated for any of the following active infections initiate ART within 2 weeks of starting OI treatment or as soon as the patient is clinically stable on OI therapy and the potential for drug-drug interactions has been minimized:.
Clinicians should consult with a care provider experienced in the management of ART in patients with these infections. Prevention of complications associated with IRIS involves careful monitoring, particularly in patients with low CD4 counts and past or current history of co-infections. To promote trust in the treatment plan and adherence to ART, patients should be informed that starting ART could lead to an initial worsening of OI symptoms or the appearance of a previously undiagnosed OI e.
Further studies are needed to more definitively determine the CD4 count threshold below which the mortality benefit supports early initiation of ART [Uthman, et al. Although the incidence of IRIS was much higher in patients who initiated ART early, it was mostly mild and was outweighed by the other benefits of early treatment.
The prednisone and ART were initiated on the same day and were initiated within 30 days of the start of TB treatment.
Use of corticosteroids was allowed to treat IRIS if it developed. The prednisone was well tolerated, and there were no additional infections or malignancies in patients receiving prednisone compared with those receiving placebo.

A frequent concern is determining the optimal timing of initiating ART in the setting of an acute OI. In a population with high mortality, early ART did not affect the mortality rate in patients with severe TB meningitis, likely due to the overall poor prognosis in this population.
In PCP, one randomized study and several retrospective studies showed a reduction in acquired immunodeficiency syndrome AIDS progression or death with early therapy. Early ART in cryptococcal disease led to increased mortality in two randomized studies in resource-limited settings.
The increased mortality appeared driven by those with the most severe disease. In individuals with less severe cryptococcal meningitis settings e. The wide range is likely due to a number of factors including the lack of a consensus case-definition for IRIS, the degree of immunosuppression prior to initiation of ART, and the burden of opportunistic infections in the population studied.
In the West, where there are relatively low rates of tuberculosis and cryptococcosis, the rates are at the low end of the range indicated. While paradoxical reactions also occur in HIV-uninfected individuals initiating antituberculous therapy, these reactions are more common in HIV-infected patients.
It may be difficult to distinguish between the unmasking of a subclinical infection that was present before initiation of ART versus new acquisition of disease as TB occurs at increased rates in all stages of HIV disease.
Accessed 9 June Paradoxical TB IRIS is often characterized by the return of constitutional symptoms and the worsening of respiratory symptoms with worsening parenchymal lesions or enlargement of intrathoracic lymph nodes on chest X-ray.
Patients with extrapulmonary disease may have worsening lymphadenitis or pleural effusions or potentially fatal reactions such as expanding intracranial tuberculomas, peritonitis, or bowel perforation. MAC IRIS either unmasking or paradoxical presents most commonly as fever and focal and occasionally suppurating lymphadenitis cervical or abdominal in most cases , usually within the first 2 months of ART initiation.
More unusual case reports of MAC IRIS have included osteomyelitis, vertebral and paravertebral abscesses, granulomatous hepatitis, brain abscesses, worsening lung infiltrates, subcutaneous nodules, and hypercalcemia. Biopsies of involved tissues generally show relatively few acid-fast bacilli with many well-formed granulomas. Figure 1 is an example of cryptococcal IRIS. The meningitis with cryptococcal IRIS may have a higher cerebrospinal fluid white blood cell count and a lower cryptococcal antigen titer than is typical for cryptococcal meningitis in AIDS patients.
Commonly, elevated intracranial pressures are a component of the IRIS reaction. Cerebrospinal fluid fungal cultures will frequently be negative. Cryptococcal IRIS can also present with intracranial or spinal cryptococcomas. Perhaps because of the long-term persistence of cryptococcal antigen, cryptococcal IRIS can be substantially delayed after the initiation of ART reportedly up to 2 years. Typically, IRIS to PCP develops within the first 8 weeks of initiating ART, often after discontinuation of corticosteroids, and presents with recurrent cough, fever, dyspnea, and worsening chest X-ray.
It has been documented that patients develop herpes zoster infection at substantially increased frequency during the first few months of ART. Typically, the zoster involves a single dermatome and responds to aciclovir.
