Choo KS, Yew J, Tan EJH, Puar THK. Case Report: Hypercalcemia as a manifestation of acute adrenal crisis precipitated by fluconazole use, and a review of the literature. Front Endocrinol (Lausanne) 2023; 14:1168797.

Abstract
Acute adrenal crisis classically presents with vomiting, altered sensorium, and hypotension. We describe a unique case manifesting with severe hypercalcemia. Addisonian crisis was unusually precipitated by fluconazole use. We reviewed other reported cases and discuss the possible mechanisms of hypercalcemia in adrenal insufficiency. This 67-year-old man presented with fever, cough, and vomiting for 1 week and with anorexia and confusion for 3 weeks. He was hypotensive and clinically dehydrated. Investigations revealed left-sided lung consolidation, acute renal failure, and severe non-parathyroid hormone (PTH)-mediated hypercalcemia (calcium, 3.55mol/L; PTH, 0.81pmol/L). Initial impression was pneumonia complicated by septic shock and hypercalcemia secondary to possible malignancy. He received mechanical ventilation; treatment with intravenous fluids, inotropes, and hydrocortisone for septic shock; and continuous renal replacement therapy with low-calcium dialysate. Although hypercalcemia resolved and he was weaned off inotropes, dialysis, and hydrocortisone, his confusion persisted. When hypercalcemia recurred on day 19 of admission, early morning cortisol was <8 nmol/L, with low ACTH level (3.2 ng/L). Other pituitary hormones were normal. Hypercalcemia resolved 3 days after reinstating stress doses of hydrocortisone, and his mentation normalized. On further questioning, he recently received fluconazole for a forearm abscess. He previously consumed traditional medications but stopped several years ago, which may have contained glucocorticoids. He was discharged on oral hydrocortisone. Cortisol levels improved gradually, and glucocorticoid replacement was ceased after 8 years, without any recurrence of hypercalcemia or Addisonian crisis. Both hypercalcemia and adrenal insufficiency may present with similar non-specific symptoms. It is important to consider adrenal insufficiency in hypercalcemia of unclear etiology.

Abstract
INTRODUCTION Adrenal insufficiency (AI) is a potentially life-threatening endocrine abnormality rarely associated with azole antifungals. Patients undergoing allogeneic hematopoietic cell transplantation (alloHCT) are at high risk of invasive fungal infection and frequently receive azoles. Signs and symptoms of AI, such as gastrointestinal symptoms, lethargy, and electrolyte disturbances frequently overlap with common alloHCT toxicities, such that azole-induced AI may be under-reported in this population. CASE REPORT We report the first published case of azole-induced AI following alloHCT. The patient presented with orthostasis and nonspecific gastrointestinal and failure to thrive symptoms in the setting of roughly 6 weeks of fluconazole prophylaxis. The patient was found to have primary AI diagnosed via low serum cortisol and inadequate response to cosyntropin. MANAGEMENT & OUTCOME AI symptoms resolved with hydrocortisone supplementation and recurred upon rechallenge with fluconazole. The patient had fluconazole permanently discontinued with resolution of symptoms. We rate this case as a probable adverse drug reaction on the Naranjo scale. DISCUSSION AI may be underreported and misdiagnosed in the alloHCT population given the presence of multiple toxicities with overlapping features. Clinicians must be diligent in investigating adrenal function in patients undergoing alloHCT on azole antifungals who present with symptoms of AI.

Abstract
A 56-year-old Hispanic man with a history of disseminated coccidioidomycosis was diagnosed with persistent glucocorticoid insufficiency and pseudohyperaldosteronism secondary to posaconazole toxicity. This case was notable for unexpected laboratory findings of both pseudohyperaldosteronism and severe glucocorticoid deficiency due to posaconazole’s mechanism of action on the adrenal steroid synthesis pathway. Transitioning to fluconazole and starting hydrocortisone resolved the hypokalemia but not his glucocorticoid deficiency. This case highlights the importance of recognizing iatrogenic glucocorticoid deficiency with azole antifungal agents and potential long term sequalae.

Abstract
BACKGROUND Cushing's disease is associated with an increased risk of pulmonary fungal infection, which could be a relative contraindication for pituitary adenoma excision surgery. CASE We report a case of a patient with Cushing's disease and pulmonary Cryptococcus neoformans. A 48-year-old woman was admitted to our hospital because of moon face and edema. Laboratory and radiological findings suggested a diagnosis of Cushing's disease and pulmonary cryptococcus infection. Fluconazole 400 mg per day was administered intravenously and continued orally for 3 months. Both cryptococcus infection and hypercortisolism relieved and transsphenoidal resection was performed. CONCLUSION Cushing's disease can be effectively treated with fluconazole to normalize cortisol concentration prior to pituitary surgery. Fluconazole is an alternative treatment especially in Cushing's disease patients with cryptococcal pneumonia.

Posaconazole-Induced Adrenal Insufficiency in a Case of Chronic Myelomonocytic Leukemia. Case Rep Endocrinol 2018; 2018:2170484.

Abstract
Introduction Posaconazole is an azole used in treatment and prophylaxis of a broad spectrum of fungal infections. Antifungals such as ketoconazole have been shown to cause primary adrenal insufficiency (AI) as a result of direct inhibition on the steroidogenesis pathway. There is only one reported case of primary AI induced by posaconazole in a patient with mucormycosis. We report a case of posaconazole-related primary AI. Case A 63-year-old man with chronic myelomonocytic leukemia was admitted for fatigue and intermittent nausea and vomiting. He had recently discontinued prophylactic posaconazole 300 mg daily. He was assessed for AI with a morning cortisol of 1.9 mcg/dL followed by a failed cosyntropin stimulation (CS) test. Adrenocorticotropic hormone (ACTH) level was 154.6 pg/mL with negative 21-hydroxylase antibodies. The patient's symptoms improved with initiation of hydrocortisone and fludrocortisone. One year after discontinuation of posaconazole, he underwent a repeat CS test which showed normal adrenal function with normal ACTH at 34.1 pg/mL. Conclusion In this case, we demonstrate that prolonged use of posaconazole is associated with primary AI. As use of posaconazole increases, knowledge of the potential risk of AI is important and must be included in the differential diagnosis when these patients present with hypotension, hypoglycemia, and failure to thrive.

Abstract
BACKGROUND Glucocorticoids play a major role in the treatment of acute lymphoblastic leukaemia (ALL). However, supraphysiological doses can suppress the hypothalamic-pituitary-adrenal (HPA) axis. HPA axis suppression resulting in reduced cortisol response may cause an impaired stress response and an inadequate host defence against infection, which remain a cause of morbidity and death. Suppression commonly occurs in the first days after cessation of glucocorticoid therapy, but the exact duration is unclear. This review is the second update of a previously published Cochrane review. OBJECTIVES To examine the occurrence and duration of HPA axis suppression after (each cycle of) glucocorticoid therapy for childhood ALL. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 11), MEDLINE/PubMed (from 1945 to December 2016), and Embase/Ovid (from 1980 to December 2016). In addition, we searched reference lists of relevant articles, conference proceedings (the International Society for Paediatric Oncology and the American Society of Clinical Oncology from 2005 up to and including 2016, and the American Society of Pediatric Hematology/Oncology from 2014 up to and including 2016), and ongoing trial databases (the International Standard Registered Clinical/Social Study Number (ISRCTN) register via http://www.controlled-trials.com, the National Institutes of Health (NIH) register via www.clinicaltrials.gov, and the International Clinical Trials Registry Platform (ICTRP) of the World Health Organization (WHO) via apps.who.int/trialsearch) on 27 December 2016. SELECTION CRITERIA All study designs, except case reports and patient series with fewer than 10 children, examining effects of glucocorticoid therapy for childhood ALL on HPA axis function. DATA COLLECTION AND ANALYSIS Two review authors independently performed study selection. One review author extracted data and assessed 'Risk of bias'; another review author checked this information. MAIN RESULTS We identified 10 studies (total of 298 children; we identified two studies for this update) including two randomised controlled trials (RCTs) that assessed adrenal function. None of the included studies assessed the HPA axis at the level of the hypothalamus, the pituitary, or both. Owing to substantial differences between studies, we could not pool results. All studies had risk of bias issues. Included studies demonstrated that adrenal insufficiency occurs in nearly all children during the first days after cessation of glucocorticoid treatment for childhood ALL. Most children recovered within a few weeks, but a small number of children had ongoing adrenal insufficiency lasting up to 34 weeks.Included studies evaluated several risk factors for (prolonged) adrenal insufficiency. First, three studies including two RCTs investigated the difference between prednisone and dexamethasone in terms of occurrence and duration of adrenal insufficiency. The RCTs found no differences between prednisone and dexamethasone arms. In the other (observational) study, children who received prednisone recovered earlier than children who received dexamethasone. Second, treatment with fluconazole appeared to prolong the duration of adrenal insufficiency, which was evaluated in two studies. One of these studies reported that the effect was present only when children received fluconazole at a dose higher than 10 mg/kg/d. Finally, two studies evaluated the presence of infection, stress episodes, or both, as a risk factor for adrenal insufficiency. In one of these studies (an RCT), trial authors found no relationship between the presence of infection/stress and adrenal insufficiency. The other study found that increased infection was associated with prolonged duration of adrenal insufficiency. AUTHORS' CONCLUSIONS We concluded that adrenal insufficiency commonly occurs in the first days after cessation of glucocorticoid therapy for childhood ALL, but the exact duration is unclear. No data were available on the levels of the hypothalamus and the pituitary; therefore, we could draw no conclusions regarding these outcomes. Clinicians may consider prescribing glucocorticoid replacement therapy during periods of serious stress in the first weeks after cessation of glucocorticoid therapy for childhood ALL to reduce the risk of life-threatening complications. However, additional high-quality research is needed to inform evidence-based guidelines for glucocorticoid replacement therapy.Special attention should be paid to patients receiving fluconazole therapy, and perhaps similar antifungal drugs, as these treatments may prolong the duration of adrenal insufficiency, especially when administered at a dose higher than 10 mg/kg/d.Finally, it would be relevant to investigate further the relationship between present infection/stress and adrenal insufficiency in a larger, separate study specially designed for this purpose.

Abstract
Adrenal crisis is a life-threatening medical emergency, associated with a high mortality unless it is appropriately recognized and early treatment is rendered. Despite it being a treatable condition for almost 70 years, failure of adequate preventive measures or delayed treatment has often led to unnecessary deaths. Gastrointestinal illness is the most common precipitant for an adrenal crisis. Although most patients are educated about "sick day rules," patients, and physicians too, are often reluctant to increase their glucocorticoid doses or switch to parenteral injections, and thereby fail to avert the rapid deterioration of the patients' condition. Therefore, more can be done to prevent an adrenal crisis, as well as to ensure that adequate acute medical care is instituted after a crisis has occurred. There is generally a paucity of studies on adrenal crisis. Hence, we will review the current literature, while also focusing on the incidence, presentation, treatment, prevention strategies, and latest recommendations in terms of steroid dosing in stress situations.

Abstract
UNLABELLED Cushing's syndrome (CS) due to ectopic ACTH production accounts for about 10% of all types of CS and is frequently associated with metabolic alkalosis. Treatment of CS involves surgical resection and/or medical therapy to control hypercortisolism. We present the case of an 80-year-old woman affected by CS due to an unknown cause. The patient had severe metabolic alkalosis with refractory hypokalemia. To treat the underlying CS, fluconazole was initiated due to unavailability of ketoconazole. In spite of markedly decreasing cortisol levels, metabolic alkalosis persisted. Treatment of metabolic alkalosis with acetazolamide was thus initiated and pH levels successfully lowered. This case report shows that hypercortisolism can be effectively treated with fluconazole in cases where ketoconazole is unavailable or not tolerated and that persistent severe metabolic alkalosis caused by glucocorticoid excess can be safely and successfully treated with acetazolamide. LEARNING POINTS Hypercortisolism can be effectively treated with fluconazole where ketoconazole is unavailable or not tolerated.Glucocorticoid excess can cause severe metabolic alkalosis.Persistent severe metabolic alkalosis can be safely and successfully treated with acetazolamide.

Abstract
BACKGROUND Glucocorticoids are essential in protocols of therapy of acute lymphoblastic leukemia (ALL). OBJECTIVES To assess the incidence, severity, morbidity, and risk factors of hypothalamic-pituitary-adrenal axis (HPA) suppression in children with ALL, and the time course of recovery. DESIGN Forty standard risk ALL children treated in the Pediatric Hematology/Oncology Unit, Ain-Shams University, Egypt, were classified into dexamethasone (DXM) group: 20 patients on children cancer group protocol and prednisone (PDN) group: 20 patients on modified Berlin-Frankfurt-Muenster (BFM) study group 90 protocol. Patients were followed clinically and by laboratory assessment of morning s.ACTH, basal and after low-dose adrenocorticotrophic hormone stimulation test of cortisol and DHEAS, at diagnosis and every 2 weeks till adrenal recovery. RESULTS HPA recovery was earlier in PDN than DXM group (P < 0.05). In induction phases 1 and 2: 65 and 75% of PDN group recovered on week 2, while 45 and 50% of DXM group recovered in week 4. Adrenal recovery was predicted 2 weeks earlier by normalized s.DHEAS. Children below 5 years of age had earlier recovery in PDN group (P = 0.04), no age effect in DXM group. CONCLUSION Adrenal suppression is an inevitable consequence of ALL therapy. Monitoring of cortisol levels and steroid coverage during stress is recommended, and gradual steroid tapering is suggested.

Abstract
AIM Fluconazole prophylaxis of invasive fungal infections is a cornerstone of neonatal care, but in vitro studies have shown that it inhibits corticosteroid production. This study assessed whether preterm infants demonstrated an association between fluconazole administration, and its duration, and symptoms of adrenocortical insufficiency. METHODS We compared two groups who were treated before and after we introduced the use of fluconazole to our neonatal intensive care unit. Infants with a gestational age of ≤27 weeks or with a birth weight of ≤750 g were considered for the retrospective analysis. In order to assess whether the duration of prophylaxis was related to adrenocortical insufficiency, regression models were performed in all preterm infants in the fluconazole group. RESULTS The fluconazole group (n = 37) and nonfluconazole group (n = 41) were compared. No differences were found in the percentage of infants with symptoms of adrenocortical insufficiency, such as hypotension or need of vasopressor therapy. The incidence of hypotension and the use of vasopressor therapy were not related to duration of fluconazole prophylaxis. CONCLUSION Fluconazole and it duration were not associated with the incidence of symptoms related to adrenocortical insufficiency. Further prospective trials are needed to better define the relationship between fluconazole and adrenocortical insufficiency.

Abstract
BACKGROUND The authors performed a systematic search of the literature to identify the frequency of, risk of experiencing and factors associated with adrenal crises in dental patients. METHODS The authors searched PubMed and Ovid MEDLINE (1947-June 20, 2012) and Embase (1974-2012) for English-language articles related to cases of adrenal crisis in dentistry and extracted and analyzed data from the articles. The six authors determined whether the cases identified met a consensus definition of adrenal crisis. RESULTS Of 148 articles identified in the initial screening, 34 articles were included in the final review, from which six cases met the criteria of adrenal crisis. The authors categorized four cases as "suggestive of adrenal crisis" and two cases as "consistent with adrenal crisis." Risk factors were significant adrenal insufficiency, pain, infection, having undergone an invasive procedure, having received a barbiturate general anesthetic, and poor health status and stability at the time of presentation. The authors estimated risk to be less than one in 650,000 in patients with adrenal insufficiency. CONCLUSIONS Adrenal crisis is rare in dental patients, with only six reports of it having been published in the past 66 years. Risk is associated with unrecognized adrenal insufficiency, poor health status and stability at the time of treatment, pain, infection, having undergone an invasive procedure and having received a barbiturate general anesthetic. CLINICAL IMPLICATIONS Risk of adrenal crisis is reduced through proper evaluation of the patient, identification of risk factors and following appropriate preventive measures.

Abstract
The antifungal agent ketoconazole is often used to suppress cortisol production in patients with Cushing's syndrome (CS). However, ketoconazole has serious side effects and is hepatotoxic. Here, the in vitro effects of ketoconazole and fluconazole, which might be less toxic, on human adrenocortical steroidogenesis were compared. The effects on steroidogenesis were examined in primary cultures of nine human adrenocortical tissues and two human adrenocortical carcinoma cell lines. Moreover, the effects on mRNA expression levels of steroidogenic enzymes and cell growth were assessed. Ketoconazole significantly inhibited 11-deoxycortisol (H295R cells; maximum inhibition 99%; EC(50) 0.73 μM) and cortisol production (HAC15 cells; 81%; EC(50) 0.26 μM and primary cultures (mean EC(50) 0.75 μM)). In cultures of normal adrenal cells, ketoconazole increased pregnenolone, progesterone, and deoxycorticosterone levels, while concentrations of 17-hydroxypregnenolone, 17-hydroxyprogesterone, 11-deoxycortisol, DHEA, and androstenedione decreased. Fluconazole also inhibited 11-deoxycortisol production in H295R cells (47%; only at 1 mM) and cortisol production in HAC15 cells (maximum inhibition 55%; EC(50) 35 μM) and primary cultures (mean EC(50) 67.7 μM). In the cultures of normal adrenals, fluconazole suppressed corticosterone, 17-hydroxypregnenolone, and androstenedione levels, whereas concentrations of progesterone, deoxycorticosterone, and 11-deoxycortisol increased. Fluconazole (1 mM) slightly increased STAR mRNA expression in both cell lines. Neither compound affected mRNA levels of other steroidogenic enzymes or cell number. In conclusion, by inhibiting 11β-hydroxylase and 17-hydroxylase activity, pharmacological concentrations of fluconazole dose dependently inhibit cortisol production in human adrenocortical cells in vitro. Although fluconazole seems less potent than ketoconazole, it might become an alternative for ketoconazole to control hypercortisolism in CS. Furthermore, patients receiving fluconazole because of mycosis might be at risk for developing adrenocortical insufficiency.

Abstract
BACKGROUND Glucocorticoids play a major role in the treatment of acute lymphoblastic leukaemia (ALL). However, supraphysiological doses may cause suppression of the hypothalamic-pituitary-adrenal (HPA) axis. HPA axis suppression resulting in reduced cortisol response may cause an impaired stress response and an inadequate host defence against infections, which remains a cause of morbidity and death. The exact occurrence and duration of HPA axis suppression after glucocorticoid therapy for childhood ALL are unclear. OBJECTIVES To examine the occurrence and duration of HPA axis suppression after (each cycle of) glucocorticoid therapy for childhood ALL. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (in The Cochrane Library, issue 3, 2010), MEDLINE/PubMed (from 1945 to July 2010) and EMBASE/Ovid (from 1980 to July 2010). In addition, we searched reference lists of relevant articles, conference proceedings and ongoing trial databases. SELECTION CRITERIA All study designs, except case reports and patient series with fewer than 10 patients, examining the effect of glucocorticoid therapy for childhood ALL on the HPA axis function. DATA COLLECTION AND ANALYSIS Two review authors independently performed the study selection. One review author performed the data extraction and 'Risk of bias' assessment, which was checked by another review author. MAIN RESULTS We identified seven studies (total number of participants = 189), including one randomised controlled trial (RCT), which assessed the adrenal function. None of the studies assessed the HPA axis at the level of the hypothalamus, pituitary, or both. Due to substantial differences between studies, results could not be pooled. All studies had some methodological limitations. The included studies demonstrated that adrenal insufficiency occurs in nearly all patients in the first days after cessation of glucocorticoid treatment for childhood ALL. The majority of patients recovered within a few weeks, but a small amount of patients had ongoing adrenal insufficiency lasting up to 34 weeks. In the RCT, the occurrence and duration of adrenal insufficiency did not differ between the prednisolone and dexamethasone arms. In one study included in the review it appeared that treatment with fluconazole prolonged the duration of adrenal insufficiency. AUTHORS' CONCLUSIONS Based on the available evidence, we conclude that adrenal insufficiency commonly occurs in the first days after cessation of glucocorticoid therapy for childhood ALL, but the exact duration is unclear. Since no data on the level of the hypothalamus and the pituitary were available we cannot make any conclusions regarding those outcomes. Clinicians should consider prescribing glucocorticoid replacement therapy during periods of serious stress in the first weeks after cessation of glucocorticoid therapy for childhood ALL, to reduce the risk of life-threatening complications. However, more high-quality research is needed for evidence-based guidelines for glucocorticoid replacement therapy.Special attention should be paid to patients receiving fluconazole therapy, and perhaps similar antifungal drugs, as this may prolong the duration of adrenal insufficiency.

Abstract
A 52-year-old man with well-controlled HIV infection taking ritonavir and increasing doses of inhaled fluticasone for chronic bronchitis developed thrush. Within days of discontinuing fluticasone and initiating fluconazole, he presented with fatigue, malaise, lower-extremity oedema and orthostasis. Testing confirmed exogenous Cushing's syndrome and secondary adrenal insufficiency. Although ritonavir–fluticasone interactions have been previously reported as a cause for adrenal insufficiency, we propose that fluconazole increased the rapidity of onset and severity of symptoms through synergistic inhibition of the adrenal axis.

Abstract
BACKGROUND A 4-week course of high-dose glucocorticoids may cause prolonged adrenal suppression even after a 9-day tapering phase. In this study, adrenal function and signs and symptoms of adrenal insufficiency were prospectively assessed in children with acute lymphoblastic leukemia (ALL) after induction treatment including high-dose prednisone (PDN) or dexamethasone (DXM). PROCEDURES Sixty-four children with ALL, treated according to the AIEOP ALL 2000 Study protocol, underwent low dose ACTH (LD-ACTH) stimulation 24 hr after the last tapered steroid dose. In those with impaired cortisol response, additional LD ACTH tests were performed every 1-2 weeks until cortisol levels normalized. Signs and symptoms of adrenal insufficiency were recorded during the observation period. RESULTS All patients had normal basal cortisol values at diagnosis. Twenty-four hours after last glucocorticoid dose, morning cortisol was reduced in 40/64 (62.5%) patients. LD-ACTH testing showed adrenal suppression in 52/64 (81.5%) patients. At the following ACTH test 7-14 days later, morning cortisol values were reduced in 8/52 (15.4%) patients and response to the test was impaired in 12/52 (23%). Adrenal function completely recovered in all patients within 10 weeks. No difference was found between patients treated with PDN or DXM. Almost 35% of children with impaired cortisol values at the first test developed signs or symptoms of adrenal insufficiency. One child developed a severe adrenal crisis during adrenal suppression. CONCLUSIONS High-dose glucocorticoid therapy in ALL children may cause prolonged adrenal suppression and related clinical symptoms. Laboratory monitoring of cortisol levels and steroid coverage during stress episodes may be indicated.

Abstract
A 38 year old man with history of obstructive sleep apnea and polycythaemia presented with hypercapnic respiratory failure that required intubation. He developed fever with infiltrates on chest radiography that required empiric antifungal therapy with fluconazole along with broad spectrum antibiotics. He developed acute adrenal insufficiency that recovered after fluconazole was stopped. It is believed that this complication of adrenal suppression attributable to fluconazole is underrecognised and it may be prudent to monitor all critically ill patients who are given fluconazole for this complication.

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
Dermatologic diseases encompass a broad category of pathologic situations. Infection remains a significant aspect of the pathology faced in patient encounters, and it is natural to expect that anti-infectives play a major element in the armamentarium utilized by dermatologists. Aside from the treatment of the classic bacterial and fungal infections, there are now new uses for antiviral agents to help suppress recurrent disease, such as herpes simplex. There is also the novel approach of using anti-infectives, or agents that have been thought to have antimicrobial activity, to treat inflammatory diseases. This review describes anti-infectives, beginning with common antibiotics used to treat bacterial infections. The discussion will then cover the current use of antivirals. Finally, the description of antifungals will be separated, starting with the oral agents and ending with the topical antimycotics. The use of anti-infectives in tropical dermatology has been purposefully left out, and perhaps should be the subject of a separate review. Cutaneous bacterial infections consist chiefly of those microorganisms that colonize the skin, such as species of staphylococcus and streptococcus. Propionibacterium acnes and certain other anaerobes can be involved in folliculitis, pyodermas and in chronic conditions such as hidradenitis suppurativa.

Abstract
Fluconazole is widely used in the intensive care unit for prevention and treatment of fungal infections. Case reports have described an association between fluconazole and adrenal dysfunction, an important cause of morbidity and mortality in critically ill patients. We sought to determine whether 400 mg of fluconazole per day administered to critically ill surgical patients was associated with a reduction in cortisol levels. Cortisol levels were measured in stored plasma specimens drawn from 154 critically ill surgical patients randomized in 1998-1999 to receive fluconazole or placebo for the prevention of candidiasis. The primary outcome measure was the median plasma cortisol level > or =1 day after study drug initiation (MPCL). Secondary outcomes were adrenal dysfunction, defined as an MPCL of <15 microg/dl, changes in cortisol levels over time, and mortality. The median MPCL was 15.75 microg/dl (interquartile range [IQR], 11.65 to 21.33 microg/dl) in 79 patients randomized to fluconazole and 16.71 microg/dl (IQR, 11.67 to 23.00 microg/dl) in 75 patients randomized to placebo (P = 0.52). Patients randomized to fluconazole did not have significantly increased odds of adrenal dysfunction compared to patients randomized to placebo (odds ratio, 0.98; 95% confidence interval, 0.48 to 2.01). Randomization to fluconazole was not associated with a significant difference in cortisol level changes over time. Mortality was not different between patients with and without adrenal dysfunction, nor was it different between patients with adrenal dysfunction who were randomized to fluconazole and those randomized to placebo. Fluconazole prophylaxis in this population of critically ill surgical patients did not result in significant adrenal dysfunction.

Abstract
BACKGROUND Glucocorticoids are commonly used in the treatment of childhood acute lymphoblastic leukemia (ALL). The purpose of this study was to assess the incidence of adrenal insufficiency and the time for children with ALL to recover after treatment with the glucorticoids prednisolone or dexamethasone. PROCEDURE Seventeen children, 2-15 years, with ALL were studied after receiving prednisolone (60 mg/m(2)/day, n = 10) for 5 weeks during remission induction therapy or dexamethasone (10 mg/m(2)/day, n = 7) for 3 weeks during reinduction therapy. Both drugs were tapered over 9 days. The adrenal function was assessed by an ACTH stimulation test within 2 weeks after discontinuing glucocorticoid therapy. In case of adrenal insufficiency, the ACTH test was repeated at 3-5 weeks interval, and patients were put on hydrocortisone substitution therapy. RESULTS Three out of ten patients had a normal adrenal function within the first 2 weeks after prednisolone therapy. Another three patients recovered within 7 weeks, whereas the remaining four patients still showed adrenal insufficiency at the end of follow-up after 2.5-4 months. For dexamethasone, two out of seven patients showed a normal adrenal function within the first 2 weeks. Of the remaining patients, two recovered within 7 weeks, whereas three patients still had a demonstrated adrenal insufficiency at the end of follow-up after 4-8 months. CONCLUSIONS Adrenal insufficiency occurs and may persist for several months in children with ALL after treatment with high doses of prednisolone or dexamethasone.
