The acquired immunodeficiency syndrome (AIDS) is a severe disease. Lung, brain and digestive complaints that result in opportunistic infections and neoplasms are the most documented. The endocrine disorders, the description of which is recent on the basis of post-mortem data, motivated some authors to undertake studies in order to evaluate endocrine function in patients infected with human immunodeficiency virus (HIV). An increase in serum cortisol level due to stress adaptation in the early stage of the disease is reported, whereas peripheral adrenal insufficiency, although unusual, appears in the late stage. Hypogonadism is common in men with HIV infection but its origin is discussed, central or peripheral. The thyroid function is generally preserved, but low T3 syndrome which correlates with bad prognosis may be observed. Anterior hypopituitarism, which is rare, hyponatremia more frequent because of its etiopathogenic factors in AIDS, constant and precocious hyperprolactinemia, are noticed. The episodes of asymptomatic or severe hypoglycemia may be explained by inanition and side effects of drugs. The non-specificity of the clinical manifestations of endocrine dysfunction masked by the classic signs of AIDS, shouldn't make forget the systematic search of glandular abnormalities as soon as an evocative symptomatology is conspicuous. The mechanisms of endocrine complications are badly known, but opportunistic infections, drugs, particularities related to the structure of HIV and interleukin 1 (IL1) surely play a role. The recognition of endocrine disorders is essential for optimal therapy because, unknown, their evolution is dramatic.

The causes and management of endocrine disorders associated with human immunodeficiency virus (HIV) infection are reviewed. Endocrine disorders observed in HIV-positive patients include adrenal abnormalities, hyporeninemic hypoaldosteronism, pituitary insufficiency, pancreatic abnormalities, thyroid and parathyroid disorders, and testicular abnormalities. Opportunistic pathogens implicated in these disorders include cytomegalovirus, Cryptococcus, Toxoplasma, mycobacteria, Candida, and Aspergillus. Neoplasma such as Kaposi's sarcoma and lymphoma can also cause endocrine abnormalities. Several drugs used in patients with the acquired immunodeficiency syndrome (AIDS) are associated with the development of endocrine disorders. These drugs include ketoconazole, itraconazole, rifampin, vidarabine, pentamidine, trimethoprim-sulfamethoxazole, didanosine, and ganciclovir. Severe patient debilitation can contribute to the development of endocrine abnormalities. Monitoring of adrenal gland function may be prudent in HIV-infected patients who have nonspecific symptoms of adrenal insufficiency. If adrenal insufficiency is diagnosed, replacement therapy with oral hydrocortisone is required. Administration of fludrocortisone can rapidly alleviate the signs and symptoms of hyporeninemic hypoaldosteronism. Fluid restriction is the first step in managing the pituitary abnormality known as the syndrome of inappropriate secretion of antidiuretic hormone. Drug-induced endocrine abnormalities often resolve after withdrawal of the offending agent. Endocrine complications in HIV-infected patients may be caused by infection, malignancy, or drugs. Adjusting or instituting drug therapy may be necessary to control symptomatic endocrine abnormalities.

Several studies have demonstrated diminished gonadal or adrenal function in patients infected with the human immunodeficiency virus (HIV). We have evaluated gonadal and adrenal function in 18 unselected ambulatory patients seropositive for HIV and clinically categorized as asymptomatic (n = 6), AIDS-related complex (ARC, n = 8) or acquired immunodeficiency syndrome (AIDS, n = 4). None of the patients was critically ill at the time of the hormone studies. Adrenal function was assessed using the 30 minute ACTH-test, and gonadal function by determination of the free testosterone serum level, both simple screening tests easily performable in practice. All male patients had normal free testosterone serum levels. In 5 (29%) of 17 patients (one asymptomatic, 3 with ARC, and 1 with AIDS) serum cortisol concentrations responded subnormally to synthetic ACTH, suggesting diminished adrenal cortisol reserve. The etiological role of the cytomegalovirus (CMV), which is said to be the most frequent cause of adrenal insufficiency in these patients, was unclear in our patients, because 4 of the 5 cases with the subnormal as well as 11 of the 12 with the normal test had antibodies against CMV in serum.

To evaluate whether frank or subtle disorders of adrenal steroidogenesis exist in human immunodeficiency virus (HIV)-infected children, the adrenal steroid response to an iv bolus of ACTH-(1-24) (0.25 mg Cortrosyn) was determined. Ten children (six males and four females, aged 7 months to 7.5 yr) were studied. Five underwent repeat testing 3-5 months after initial assessment. Nine patients were classified as P2 or symptomatic according to the Center for Disease Control criteria for HIV infection in children. Eight had failure to thrive, six had opportunistic infections and neurological deficits, and two were receiving ketoconazole at the time of ACTH testing. Only one patient had a neonatally acquired transfusion-related HIV infection. Three of the children died 2-5 months after ACTH testing. All patients had normal or slightly elevated baseline and stimulated cortisol levels compared to the control population. The mean post-ACTH cortisol level was significantly higher than the mean post-ACTH level in the control population. No patient demonstrated an impaired aldosterone response to ACTH. The basal and ACTH-stimulated dehydroepiandrosterone levels were normal. Although individual deoxycorticosterone and corticosterone levels were variable, the mean stimulated deoxycorticosterone and corticosterone levels in the patients were suggestive of a selective defect of the 17-desoxy pathway in the adrenal fasciculata. No changes were noted in the patients' cortisol, dehydroepiandrosterone, and aldosterone responses on repeat ACTH testing. In HIV-infected children we have demonstrated that cortisol and aldosterone synthesis is intact. Thus, the chronic debilitation observed cannot be explained on the basis of adrenal insufficiency. However, a selective deficiency of 17-desoxysteroid hormone production from the adrenal fasciculata may be present.(ABSTRACT TRUNCATED AT 250 WORDS)

A group of 217 patients seropositive for human immunodeficiency virus (HIV) were studied for 2 years, during which time pigmented lesions of the oral mucosa developed in 14 (6.4%) of them. The lesions were well circumscribed in some cases and diffuse in others. In some patients the macules enlarged or recurred after surgical excision. In two patients the macules appeared during the administration of zidovudine. Clinical and laboratory evidence of adrenal insufficiency was not detected in any of the patients examined. The histologic appearances were those of melanotic macules. No ultrastructural alterations of the melanocytes were observed. Two of these macules also contained Epstein-Barr virus, and in one case normal oral mucosa was examined and also contained Epstein-Barr virus in the epithelial cells. As a control group we examined 180 health care workers who did not belong to any risk category, and 30 intravenous drug abusers who tested seronegative to HIV. Oral melanotic pigmentation was found in eight of the control subjects (3.6%). The difference was not statistically significant (p = 0.3097). Our study shows that oral macules do not occur more frequently in HIV-infected patients. However, the clinical behavior of these lesions appears to be different during the course of HIV infection. In some HIV-infected patients the cause of the macules might relate to the administration of zidovudine and antifungal or antibacterial drugs. In others the cause remains unknown and could be due to multiple factors.

We performed prospective and retrospective studies of 96 consecutive patients with acquired immune deficiency syndrome (AIDS) or AIDS-related complex (ARC) to determine the incidence, pathogenesis, and clinical significance of hyponatremia, defined as serum sodium levels less than or equal to 130 mmol/L on more than one occasion. Thirty (31.3%), six with ARC and 24 with AIDS, had hyponatremia, and it developed in 20 as outpatients. Age, gender, duration of illness, and weight loss did not differ between groups. The hyponatremic patient had more opportunistic illnesses, including Pneumocystis carinii pneumonia and cytomegalovirus infections, and had a mortality of 70% as compared to 36.4% of the patients without hyponatremia. The probability of 50% survival after diagnosis of human immunodeficiency virus (HIV) infection in the hyponatremic group was 11.5 months, as compared to 39 months for those without hyponatremia, p less than 0.001. The probability of 50% survival after development of hyponatremia was 4.5 months and the median length of time to development of hyponatremia was 12.5 months after diagnosis of HIV infection. Eighty-eight percent had hypovolemia and 12% normovolemia. Seventeen of 21 with hypovolemia had no evident source of fluid loss. Two had Addison's disease, and 15 had unexpectedly high urine sodium concentration without evidence of renal or adrenal insufficiency. Hyponatremia occurs commonly in ambulatory patients with ARC or AIDS, appears in patients with higher mortality and morbidity, and does not represent a terminal event. Most patients had hypovolemia and unexpectedly high urine sodium concentration, suggesting defective renal sodium conservation.

Since the first report on the acquired immunodeficiency syndrome (AIDS) in 1981, organ involvement of AIDS has increased. We discuss the effect of human immunodeficiency virus (HIV) infection, the causative agent of AIDS, on the field of nephrology. Hyponatremia, the commonest fluid and electrolyte abnormality, is caused by various pathophysiologic mechanisms, including adrenal insufficiency. The renal parenchymal complications are diverse, but a new entity, HIV-associated nephropathy, is becoming recognized because of its characteristic clinical and pathologic features, including the fact that it causes irreversible renal failure. HIV infection in patients with end-stage renal failure, both before and after initiation of maintenance dialysis, is a significant problem. The present methods of preventing spread of virus in dialysis units seem successful. Few patients who are infected with HIV or who have AIDS have had renal transplantation, although unsuspected viral infection of cadaveric organs remains a concern.

The authors report the case of a child who, at the age of 18 months showed signs of hypoparathyroidism together with gastrointestinal, then buccal, then ungual candidiasis. Acute adrenal failure occurred when he was 5 1/2 years' old. At the age of 10, the patient developed alopecia areata and interstitial keratitis. Immunological investigations yielded normal results, except that serum was weakly positive for anti-adrenal antibodies at 1/10th. The mucosal and ungual candidiasis infection was cured by ketoconazole, and the various endocrine abnormalities were corrected with the appropriate replacement therapies. This case prompted the authors to review the candidiasis/"polyglandular autoimmune disease" association. Whitaker's triad consists of candidiasis, hypoparathyroidism and chronic renal failure, 2 or these 3 elements being sufficient to make the diagnosis. Numerous other associations have been described; they are presented here in table form in descending order of frequency, with candidiasis/hypoparathyroidism coming on top of the list (70 p. 100). The fairly constant chronological order in which these different pathologies appear is one of the peculiarities of the syndrome: candidiasis often precedes hypoparathyroidism and adrenal insufficiency. Alopecia areata does not seem to be frequent, but its true incidence is difficult to quantify since lesions of the scalp and/or skin appendages are poorly documented in the literature. Alopecia and keratopathy seem to be of autoimmune origin. Mucocutaneous candidiasis too is specific, the mucosae and nails being constantly involved. This type of candidiasis does not exist in other forms of hypoparathyroidism. Chronic mucocutaneous candidiasis is found in many different diseases and is due to immunodeficiency against Candida spp.(ABSTRACT TRUNCATED AT 250 WORDS)

Forty-one homosexual men with the acquired immune deficiency syndrome (AIDS) or AIDS-related complex were treated with 0.5, 1.0, or 1.5 g of suramin weekly for up to six months. In no patient was evidence of symptomatic improvement or regression of Kaposi's sarcoma shown. Opportunistic infections developed in 16 patients during therapy. Only six patients (15 percent) became human immunodeficiency virus (HIV) culture-negative during treatment, despite documentation of adequate serum suramin levels. All but one of these six have had disease progression. Decreases in the numbers of total T4 cells with time were observed in both AIDS and AIDS-related complex subgroups. Toxicity was significant and consisted of fatigue, fever, and hepatic and renal dysfunction, all of which were observed most frequently with the 1.0 or 1.5 g dosages. Fatal hepatic failure developed in two patients, and adrenal insufficiency was documented in eight patients. Suramin is a toxic agent that shows no virologic, immunologic, or clinical benefit in patients with HIV-related disease.

Suramin sodium is a reverse transcriptase inhibitor with in vitro activity against the human immunodeficiency virus (HIV), the causative agent of acquired immunodeficiency syndrome (AIDS). Ninety-eight patients with AIDS manifest as opportunistic infections (n = 38), AIDS with Kaposi's sarcoma (n = 38), AIDS-related complex (n = 20), or AIDS-associated non-Hodgkin's lymphoma (NHL) (n = 2) were treated with suramin sodium at 0.5, 1.0, or 1.5 g/wk for six weeks followed by maintenance therapy with 0.5 or 1.0 g/wk. Of 72 patients who were HIV culture positive before therapy and were assessable for subsequent HIV culture 40% became culture negative during treatment, with no apparent correlation between virus recovery and serum suramin concentration. No immunologic improvement was noted. One complete clinical remission was noted in a patient with Kaposi's sarcoma and stage IV NHL. Seven minor clinical responses were also noted. Toxic reactions were generally reversible, and included fever (78%), rash (48%), malaise (43%), nausea (34%), neurologic symptoms (33%), and vomiting (20%). Suramin-induced neutropenia was noted in 26%, thrombocytopenia in 12%, a serum creatinine level of 180 mumol/L or higher (greater than or equal to 2.1 mg/dL) in 12%, liver dysfunction in 14%, and clinical and/or laboratory evidence of adrenal insufficiency in 23%. Sixteen patients died while receiving suramin or within three weeks of discontinuation of drug therapy due to infection (n = 6), hepatic failure (n = 3), pulmonary Kaposi's sarcoma (n = 2), AIDS encephalitis (n = 2), AIDS-associated NHL (n = 1), iatrogenic hemo-pneumothorax (n = 1), or pulmonary disease of uncertain etiology. Suramin as currently administered cannot be recommended as effective therapy for AIDS.
