Prevalence, Clinical Features, and Predictors of Adrenal Insufficiency in Adults With Tuberculosis or HIV: A Systematic Review and Meta-analysis. Open Forum Infect Dis 2024; 11:ofae098.

Abstract
Background Despite the high frequency of adrenal insufficiency (AI) in patients with tuberculosis or HIV, its diagnosis is often missed or delayed resulting in increased mortality. This systematic review and meta-analysis aimed to document the prevalence, significant clinical features, and predictors of AI in adult patients with tuberculosis or HIV. Methods We systematically searched databases (Medline, Embase, CINAHL, Cochrane Library, and Africa Journal Online) for published studies on AI in adult patients with tuberculosis or HIV. The pooled prevalence of AI was determined by a random-effect model meta-analysis. A narrative review was used to describe the significant clinical features and predictors of AI in adult patients with tuberculosis or HIV. Results A total of 46 studies involving 4044 adults were included: 1599 with tuberculosis and 2445 with HIV. The pooled prevalence of AI was 33% (95% CI, 22%-45%; I2 = 97.7%, P < .001) in participants with tuberculosis and 28% (95% CI, 18%-38%; I2 = 98.9%, P < .001) in those with HIV. Presentation with multidrug-resistant tuberculosis, abdominal pain, salt craving, myalgia, increased severity and duration of tuberculosis disease, and the absence of nausea predicted AI in participants with tuberculosis in 4 studies. Cytomegalovirus antigenemia positivity, rifampicin therapy, and eosinophilia >3% predicted AI in participants with HIV in 2 studies. Conclusions AI is relatively common in adults with tuberculosis or HIV. Its timely screening, diagnosis, and management in patients with these 2 conditions should be encouraged to avert mortality.

Abstract
HIV infection induces hypothalamic-pituitary-adrenal (HPA) axis derangements. Partial glucocorticoid resistance has been observed in a subset of AIDS patients, possibly owing to HIV-induced altered cytokine secretion and action. Because glucocorticoids have immunomodulatory effects, the severity of the HPA axis disorder could play a central role in disease progression. The characteristic phenotype of AIDS patients (visceral obesity, lipodystrophy) may be owing to effects of HIV proteins on the HPA axis, including changes in glucocorticoid and insulin sensitivity of target tissues, as well as altered cytokine production and interaction with the HPA axis, genetic causes, comorbidities, and, possibly, use of antiretroviral agents.

Abstract
The hypothalamic pituitary adrenal (HPA) axis is the most common of the endocrine lines/axis' to be affected by HIV infection. There are multiple factors that contribute to this HPA axis dysregulation. Direct invasion of the various organs in the axis can be either by opportunistic infections or infiltrative diseases. The soluble factors or cytokines released during viral infection and the chronic inflammatory state that follows, also contribute to these alterations. The actions of these cytokines released by the immune response can both activate the HPA axis and cause a glucocorticoid resistant state. Further, many of the anti-retroviral and other medications used to treat HIV infection can contribute to HPA axis dysfunction. While the diagnosis and treatment of endocrine dysfunction is the same as in any other patient, management pathways may be quite different. While some may be adaptive responses, life threatening adrenal insufficiency can also be present. It is important the latter be picked up expeditiously and treated promptly to avoid mortality.

Abstract
A novel slow-growing scotochromogenic mycobacterium was isolated from skin biopsies from a patient with a history of Hodgkin's disease and severe cellular immunodeficiency as an opportunistic pathogen. Clinical characterization of these lesions revealed papules and nodules with pathological granuloma formation. Genotypic analysis using 16S rRNA misidentified this isolate as Mycobacterium simiae. However, multiple gene analysis using the internal transcribed spacer between the 16S and 23S rRNA genes, and the rpoB and hsp65 genes revealed the presence of a novel mycobacterium. The antimicrobial susceptibility of this isolate was completely different from that of M. simiae. On the basis of these findings, we propose naming this new species Mycobacterium shigaense sp. nov., and conclude that multiple gene analysis is required for the appropriate diagnosis and treatment of non-tuberculous mycobacterial infections.

Abstract
Acquired primary adrenal insufficiency is a rare disorder in childhood. The most common cause is autoimmune adrenalitis, especially as a part of polyendocrinopathy syndromes. Impaired adrenal function is seen in patients infected with HIV. In adult patients with AIDS, cytomegalovirus (CMV)-associated adrenal insufficiency is a well-known condition, whereas CMV infection as a causing adrenal insufficiency in children is very rare. Here, we report an infant with transient adrenal insufficiency associated with CMV infection but without HIV. She was treated successfully with steroid replacement and ganciclovir. Early diagnosis and treatment is lifesaving in these patients.

Abstract
Adrenal insufficiency associated with cytomegalovirus (CMV) is a well-described condition in adults with AIDS, however there is little information about CMV-associated adrenal insufficiency in childhood. The cases of two infants with negative HIV serology, presenting with CMV-associated adrenal insufficiency, are described. Clinical findings and therapeutic interventions are discussed with reference to the affinity of CMV infection for the adrenal gland. The differential diagnosis of adrenal insufficiency in newborns and infants should include CMV infection, and clinical suspicion of CMV-associated adrenal insufficiency should lead to early initiation of appropriate adrenal substitution therapy and ganciclovir antiviral therapy. Timely therapy for CMV-associated adrenal insufficiency can be lifesaving.

Abstract
The presence of polyomaviruses and herpesviruses in adrenal tumors and their role in adrenal tumorigenesis has never been investigated, even though the adrenal gland seems to be a preferential site of infection by these viruses and adrenal steroid hormones have been shown to activate their replication. We examined in a large series of normal adrenal gland tissues (n=20) and adrenal tumors (n=107) the presence of herpesviruses and polyomaviruses sequences and gene expression, which were detected in a high proportion of both normal and neoplastic adrenal samples (overall, viruses were found in 15% normal adrenals, 27.8% benign adrenal tumors and 35.3% malignant tumors). The polyomaviruses SV40 and BK virus were more frequently found in malignant adrenal tumors, whereas herpesviruses, especially Epstein-Barr virus and human cytomegalovirus, were more frequently detected in functioning benign adrenocortical tumors, often as coinfection. Moreover, tumors from patients with severe hypercortisolism frequently showed herpesvirus coinfections at high viral genome copy number. Our study suggests that the adrenal gland could be a reservoir of infection for these viruses and that hormone overproduction by the adrenal gland could represent a trigger for virus reactivation. On the other hand, these viruses could also contribute to adrenal cell proliferation and tumorigenesis.

Abstract
Adrenal infections are an important but under-recognized clinical entity. The adrenal gland can be infected by a myriad of pathogens including fungi, viruses, parasites, and bacteria. Infection can directly or indirectly cause tissue damage and alteration in endocrine function. Direct damage occurs via microbial replication and local production of toxic compounds, such as endotoxins. Indirect damage results from alterations in the regulation of a host's immunologic and endocrine mediators in response to damage by a microbe at a distant site. Variations in pathogen tropism, adrenal anatomy, and host immune integrity contribute to the progression of active disease and discernable adrenal dysfunction. Early recognition and intervention in the case of adrenal infection can significantly improve outcome, demonstrating the need for increased clinical suspicion in the appropriate clinical setting.

Abstract
Despite the widespread use of vaccinia virus (VV) as a vector for other Ags and as the smallpox vaccine, there is little information available about the protective components of the immune response following VV infection. In this study, protection against wild-type VV was evaluated in mice with respect to the relative contributions of CD8(+) T cells vs that of CD4(+) T cells and Ab. C57BL/6 mice primed with the Western Reserve strain of VV mount significant IgM and IgG Ab responses, specific cytotoxic T cell responses, IFN-gamma responses in CD4(+) and CD8(+) T cells, and effectively clear the virus. This protection was abrogated by in vivo depletion of CD4(+) T cells or B cells in IgH(-/-) mice, but was not sensitive to CD8(+) T cell depletion alone. However, a role for CD8(+) T cells in primary protection was demonstrated in MHC class II(-/-) mice, where depleting CD8(+) T cells lead to increase severity of disease. Unlike control MHC class II(-/-) mice, the group depleted of CD8(+) T cells developed skin lesions on the tail and feet and had adrenal necrosis. Adoptive transfer experiments also show CD8(+) T cells can mediate protective memory. These results collectively show that both CD4(+) and CD8(+) T cell-mediated immunity can contribute to protection against VV infection. However, CD4(+) T cell-dependent anti-virus Ab production plays a more important role in clearing virus following acute infection, while in the absence of Ab, CD8(+) T cells can contribute to protection against disease.

Abstract
In human immunodeficiency virus infected individuals, human cytomegalovirus (CMV) remains a significant pathogen. The adrenal gland is a preferential site of CMV disease in acquired immunodeficiency syndrome (AIDS) patients. However, glucocorticoid replacement is often not selected because of the risk of exacerbating underlying infection. To evaluate the need for glucocorticoid replacement in these patients, we performed a prospective study to investigate the adrenal function in 60 advanced AIDS patients. Their adrenal function including rapid ACTH test (RAT), basal plasma ACTH level, and daily urinary free cortisol level was evaluated. Approximately 25% of the patients turned out to be abnormal in this evaluation. Almost 60% of the patients could be followed up for one year or until their death. Using the follow-up data, we calculated sensitivity, specificity, positive predictive value and negative predictive value. Excretion of urinary free cortisol with normal RAT was comparable to normal controls, whereas patients with abnormal RAT excreted significantly lower urinary free cortisol. During hospitalization, 14 patients with normal RAT had febrile episode. During the febrile period the concentration of the urinary free cortisol level increased by 2.2 times. This study suggests that glucocorticoid replacement is necessary for AIDS patients suspected as clinically adrenal insufficiency, and that the dose of glucocorticoid replacement might be increased during sick days in AIDS patients with abnormal adrenal function.

Abstract
A morphologic evaluation was carried out on adrenal glands from 128 autopsied patients with the acquired immunodeficiency syndrome (AIDS). The adrenal gland was compromised in 99.2% of the cases, with distinct pathological features and infectious agents. Inflammatory infiltrates were observed in 99.2% of the cases with a predominance of mononuclear cells in 97.4%, affecting mainly the medulla. Necrosis, fibrosis, hemorrhages and neoplasias were observed. We also described 3 (2.3%) cases of calcification located in the adrenal gland central vein (AGCV). This is seldom mentioned in the literature. Cytomegalovirus was the most frequent infectious agent, observed in 48.4% of cases. Balamuthia mandrillaris, a free living ameba, was found in one case affecting the entire gland. We also found a nest of Trypanosoma cruzi in the musculature of the AGCV. The presence of the nest of T cruzi in AGCV may play a role in the reactivation of this infection in immunosuppressed individuals. Pathologic processes and opportunistic infections may contribute to the alterations in the adrenal gland that lead to multiple organ failure observed in terminal AIDS patients.

Abstract
OBJECTIVE The adrenal gland is the endocrine organ most commonly involved in patients infected with human immunodeficiency virus (HIV). It is important to recognize patients with adrenal insufficiency, because this disorder may be fatal if untreated. The incidence of adrenal insufficiency in critically ill HIV-infected patients is unclear, partly because different criteria are used to diagnose adrenal insufficiency. To help clarify the incidence of adrenal insufficiency in HIV-infected critically ill patients, we compared the incidence based on the stress cortisol concentration, low-dose corticotropin stimulation test, and high-dose corticotropin stimulation test. SETTING Medical intensive care unit. PATIENTS Twenty-eight critically ill patients with HIV, mean age 43 +/- 9 years; 20 were male; 54% died. INTERVENTIONS We performed a 1-microg (low-dose adrenocorticotropic hormone; LD-ACTH) and 249 microg (high-dose; HD-ACTH) corticotropin stimulation test in HIV-infected critically ill patients not receiving corticosteroids. According to results of the stress serum cortisol concentration and LD-ACTH and HD-ACTH tests, patients were classified as having adrenal insufficiency or as normal. The results of newly revised diagnostic criteria for adrenal insufficiency (i.e., stress cortisol concentration and cortisol response to LD-ACTH <25 microg/dL) were compared with the traditional criteria (i.e., stress cortisol level and response to HD-ACTH <18 microg/dL). In addition, the associations between adrenal insufficiency and the CD4 count, human cytomegalovirus antigenemia, and other risk factors for adrenal insufficiency were determined. MEASUREMENTS AND MAIN RESULTS When we used a stress cortisol concentration <18 microg/dL as the sole diagnostic threshold for diagnosis of adrenal insufficiency, 50% (14 of 28) of patients had adrenal insufficiency. The incidence was 75% (21 of 28) when we used a diagnostic threshold of <25 microg/dL for the stress cortisol concentration. When we used both the stress cortisol concentration and LD-ACTH test with a diagnostic cortisol threshold concentration <18 microg/dL, 21% (six of 28) had adrenal insufficiency. The incidence was 46% (13 of 28) when we used a cortisol diagnostic threshold concentration of <25 microg/dL. When we used both the stress cortisol concentration and the HD-ACTH stimulation test with a diagnostic cortisol threshold of <18 microg/dL, 7% (two of 28) had adrenal insufficiency. The incidence of adrenal insufficiency was 21% (six of 28) with a cortisol diagnostic threshold value of <25 microg/dL. Human cytomegalovirus antigenemia was the only variable assessed that was associated with adrenal insufficiency. CONCLUSION There is a high incidence of adrenal insufficiency in critically ill HIV-infected patients that varies with the criteria used to diagnose adrenal insufficiency. The LD-ACTH stimulation test is more sensitive than the high-dose test for diagnosing adrenal insufficiency in this population. Because of the high incidence of inadequate adrenal function, all critically ill HIV-infected patients should undergo an evaluation for adrenal insufficiency with the stress cortisol concentration and LD-ACTH stimulation tests.

Abstract
Forty-two patients were evaluated to determine the value of the CMV antigenemia (CMV-Ag) test as a follow-up marker as well as a prediction marker of CMV disease. Twenty patients were positive for at least one positive CMV-Ag assay and 9 of them developed CMV retinitis. With the threshold value (10 positive cells), sensitivity was 56% and specificity was 94%. The CMV-Ag assay, with the threshold value, produced high specificity, positive predictive value and negative predictive value but relatively poor sensitivity. Eight patients experienced CMV disease relapse a total of 16 times. At relapse, 8 of the 16 times showed negative for CMV-Ag assay; 7 underwent systemic maintenance while 1 underwent local maintenance. It is inferred that the CMV-Ag test is a poor follow-up marker to detect the relapse of CMV disease, particularly in patients undergoing systemic maintenance.
