ABSTRACT

Neisseria cinerea is a commensal bacteria of the human oropharynx, not thought to be pathogenic, and is rarely associated with serious infections, including bacteremia. Case reports involving invasive N. cinerea infections are uncommon in the literature. Retropharyngeal abscesses are unusual in adults, and are usually attributable to local trauma.Based on a review of the literature, Neisseria cinerea bacteremia secondary to a retropharyngeal abscess has not been described. We present a unique case of an elderly female without clear predisposing factors for a retropharyngeal abscess, who presented with a N. cinerea bacteremia and was found to have an asymptomatic retropharyngeal abscess.

ABSTRACT

BACKGROUND: Pharyngeal and anorectal reservoirs of gonorrhea (GC) and chlamydia (CT) are increasingly recognized among heterosexual women. While a number of studies performed at sexually transmitted disease (STD) clinics have found a high prevalence of extragenital GC/CT infection, such screening is typically not offered during routine primary care visits for women. We sought to define the prevalence of and factors associated with extragenital GC/CT among women in the U.S. Navy. METHODS: We recruited servicewomen stationed in San Diego, California, between the ages of 18 and 25 who presented for an annual physical exam between January and September, 2017. Nucleic acid amplification testing was performed on swabs collected at endocervical, oropharyngeal and anorectal sites to assess the presence of GC/CT. An anonymous behavioral questionnaire was also administered to characterize sexual risk. Descriptive statistics were used to compare women with and without a prior history of any sexually transmitted infection (STI) (self-report) along with a current GC/CT diagnosis. This study was approved by the Institutional Review Board of the Uniformed Services University of Health Sciences. RESULTS: Of the 75 patients who were approached, 60 subjects were enrolled in the study, including white 20 (33.3%), black/African American 18 (31.0%), Hispanic/Latina 13 (21.7%) and Asian/Pacific Islander 9 (15.5%) women. Among all the women, six (10.0%) were diagnosed with CT infection, all via endocervical exam. Of these, five (8.3%) had concurrent anorectal infection, including two cases (3.3%) accompanied by pharyngeal infection. Of the subjects, 15 (25.0%) reported anal intercourse in their most recent sexual encounter, most of which was condomless (13/15, 86.7%). A high number of women who reported sex with a casual male partner (19/45, 42.2%) reported rarely or never using condoms; last, 41.7% consuming at least 3 drinks on a typical drinking day, and one-third of the reported drinking more than once per week. CONCLUSIONS: We found a high prevalence of anorectal CT infection, although no infections were detected without concurrent endocervical involvement. Nonetheless, the high prevalence of condomless anal intercourse reported by participants argues for further study and ongoing consideration of extragenital screening among high-risk patients. Behavioral interventions are also warranted given the high prevalence of sexual and related risk factors.

ABSTRACT

Angiostrongylus cantonensis is the most common cause of eosinophilic meningitis worldwide. Infection typically occurs through ingestion of undercooked molluscs or vegetables contaminated by infective larvae. Endemic regions were previously limited to southeast Asia and the Pacific basin; however, this parasite is seeing an alarming increase in global distribution with reported cases in more than 30 countries, including several states in the USA. Although infection typically results in meningitis, a broad spectrum of CNS involvement and severity is emerging as diagnostic methods (such as real-time PCR) continue to improve diagnosis. In this Grand Round, we report a case of a 20-year-old active duty US marine serving in Okinawa, Japan, afflicted with severe CNS angiostrongyliasis marked by radiculomyelitis with quadriparesis, hyperaesthesia, and urinary retention. We present this case to highlight that no clear guidelines exist for the treatment of severe CNS angiostrongyliasis and provide our consensus recommendation that treatment algorithms include use of dual corticosteroids plus anthelmintics when radicular symptoms are present. In this Grand Round we review the clinical features, epidemiology, advances to diagnostic techniques, and available data on current treatment options for CNS angiostrongyliasis. This diagnosis should be highly considered in the differential diagnosis of a patient presenting with meningeal symptoms, paraesthesia or hyperaesthesia, and CSF eosinophilia so that treatment can be started early, which is particularly important in children, because of their increased risk of severe disease and mortality. We recommend combined therapy with albendazole and prednisolone, with consideration for increased steroid dosing in severe cases.

ABSTRACT

BACKGROUND: With repeal of "Don't Ask, Don't Tell" (DADT) in 2011 and the Supreme Court decision regarding Section 3 of the Defense of Marriage Act (DOMA) in 2013, military providers are now able to openly address unique health needs of lesbian, gay, and bisexual (LGB) service members and their same-sex spouse beneficiaries. These federal laws created health care barriers, either real or perceived, between providers and patients and often limited medical research involving LGB patients in the Military Health System (MHS). Men who have sex with men (MSM), the largest proportion of LGB service members, represent a segment of the population with the highest risks for disparities in primary care with regard to sexual health and mental health disorders. We provide a review of available research about this military population, in addition to a review of specific health care needs of the MSM patient in order to aid the primary care provider with screening, testing, and counseling. METHODS: A structured literature search was conducted to identify recent literature pertaining to health needs of U.S. military MSM service members. In addition, a review of applicable clinical guidelines, Department of Defense policies, and expert opinion was used to identify areas of particular relevance. FINDINGS: There is little published to characterize the MSM population and their health needs as beneficiaries of the MHS. Only recently have directed assessments of the active-duty MSM patient population been pursued in the post-DADT, DOMA era. Unique needs of the MSM patient identified center around both sexual and mental health, disparities that are paralleled within the nonmilitary MSM population. Population-specific epidemiology driving risk for sexually transmitted illnesses, substance abuse, and mental health disorders are identified and used to inform preventive medicine recommendations for the MSM patient. In addition, resources on MSM health for the health provider are included. DISCUSSION/IMPACT/RECOMMENDATION: The MHS at large now openly serves the MSM population and is making progress toward addressing their unique health needs. Despite ongoing challenges to address remaining disparities, MSM patients, beneficiaries, and primary providers are now more able to have frank, open discussions about specific health needs of this minority segment of the U.S. military without fear of reprisal.

ABSTRACT

BACKGROUND: The effects of at-risk drinking on HIV infection remain controversial. We investigated the impact of self-reported alcohol consumption on surrogate markers of HIV progression among individuals initiated on highly active antiretroviral therapy (HAART). METHODS: We analyzed individuals who were surveyed on alcohol use within a year of HAART initiation between 2006 and 2014. At-risk drinking was defined as consumption of at least 3 or 4 drinks/d, or 7 and 14 drinks/wk among women and men, respectively. We performed time-updated generalized estimating equation logistic regression to determine the effect of at-risk drinking on virologic failure (VF) and mixed-effects linear regression on CD4 count reconstitution, controlling for potential confounders. RESULTS: Of 801 individuals initiated on HAART, 752 individuals with alcohol survey data were included in the analysis. Of these, 45% (n = 336) met criteria for at-risk drinking at HAART initiation on at least 1 survey. The rates of VF were 4.30 per 100 person-years (95% CI [2.86, 6.21]) for at-risk drinkers and 2.45 per 100 person-years (95% CI [1.57, 3.65]) for individuals without at-risk drinking. At-risk drinking was not significantly associated with VF (OR 1.73, 95% CI [0.92, 3.25]) (p = 0.087) or CD4 reconstitution (CD4 increase 11.4; 95% CI [-19.8, 42.7]) in univariate analyses; however, in our multivariate model, a statistically significant relationship between VF and at-risk drinking was observed (OR 2.28, 95% CI [ 1.01, 5.15]). CONCLUSIONS: We found a high proportion of at-risk drinking in our military cohort, which was predictive of VF in multivariate analysis. Given alcohol's effect on myriad HIV and non-HIV outcomes, interventions to decrease the prevalence of at-risk drinking among HIV-infected individuals are warranted.

ABSTRACT

Background. Few data exist on the incidence and risk factors of Staphylococcus aureus colonization and skin and soft tissue infections (SSTIs) among patients infected with human immunodeficiency virus (HIV). Methods. Over a 2-year period, we prospectively evaluated adults infected with HIV for incident S aureus colonization at 5 body sites and SSTIs. Cox proportional hazard models using time-updated covariates were performed. Results. Three hundred twenty-two participants had a median age of 42 years (interquartile range, 32-49), an HIV duration of 9.4 years (2.7-17.4), and 58% were on highly active antiretroviral therapy (HAART). Overall, 102 patients (32%) became colonized with S aureus with an incidence rate of 20.6 (95% confidence interval [CI], 16.8-25.0) per 100 person-years [PYs]. Predictors of colonization in the final multivariable model included illicit drug use (hazard ratios [HR], 4.26; 95% CI, 1.33-13.69) and public gym use (HR 1.66, 95% CI, 1.04-2.66), whereas antibacterial soap use was protective (HR, 0.50; 95% CI, 0.32-0.78). In a separate model, perigenital colonization was associated with recent syphilis infection (HR, 4.63; 95% CI, 1.01-21.42). Fifteen percent of participants developed an SSTI (incidence rate of 9.4 cases [95% CI, 6.8-12.7] per 100 PYs). Risk factors for an SSTI included incident S aureus colonization (HR 2.52; 95% CI, 1.35-4.69), public shower use (HR, 2.59; 95% CI, 1.48-4.56), and hospitalization (HR 3.54; 95% CI, 1.67-7.53). The perigenital location for S aureus colonization was predictive of SSTIs. Human immunodeficiency virus-related factors (CD4 count, HIV RNA level, and HAART) were not associated with colonization or SSTIs. Conclusions. Specific behaviors, but not HIV-related factors, are predictors of colonization and SSTIs. Behavioral modifications may be the most important strategies in preventing S aureus colonization and SSTIs among persons infected with HIV.

ABSTRACT

BACKGROUND: In outbreak settings, mass vaccination strategies could maximize health protection of military personnel. Self-administration of live attenuated influenza vaccine (LAIV) may be a means to vaccinate large numbers of people and achieve deployment readiness while sparing the use of human resources. METHODS: A phase IV, open-label, randomized controlled trial evaluating the immunogenicity and acceptance of self-administered (SA) LAIV was conducted from 2012 to 2014. SA subjects were randomized to either individual self-administration or self-administration in a group setting. Control randomized subjects received healthcare worker-administered (HCWA) LAIV. Anti-hemagglutinin (HAI) antibody concentrations were measured pre- and post-vaccination. The primary endpoint was immunogenicity non-inferiority between SA and HCWA groups. Subjects were surveyed on preferred administration method. RESULTS: A total of 1077 subjects consented and were randomized (529 SA, 548 HCWA). Subject characteristics were very similar between groups, though SA subjects were younger, more likely to be white and on active duty. The per-protocol analysis included 1024 subjects (501 SA, 523 HCWA). Post-vaccination geometric mean titers by vaccine strain and by study group (HCWA vs. SA) were: A/H1N1 (45.8 vs. 48.7, respectively; p=0.43), A/H3N2 (45.5 vs. 46.4; p=0.80), B/Yamagata (17.2 vs. 17.8; p=0.55). Seroresponses to A components were high (∼67%), while seroresponses to B components were lower (∼25%). Seroresponse did not differ by administration method. Baseline preference for administration method was similar between groups, with the majority in each group expressing no preference. At follow-up, the majority (64%) of SA subjects preferred SA vaccine. CONCLUSIONS: LAIV immunogenicity was similar for HCWA and SA vaccines. SA was well-tolerated and preferred to HCWA among those who performed SA.

ABSTRACT

BACKGROUND: HIV-infected persons have increased risk of MRSA colonization and skin and soft-tissue infections (SSTI). However, no large clinical trial has examined the utility of decolonization procedures in reducing MRSA colonization or infection among community-dwelling HIV-infected persons. METHODS: 550 HIV-infected adults at four geographically diverse US military HIV clinics were prospectively screened for MRSA colonization at five body locations every 6 months during a 2-year period. Those colonized were randomized in a double-blind fashion to nasal mupirocin (Bactroban) twice daily and hexachlorophene (pHisoHex) soaps daily for 7 days compared to placeboes similar in appearance but without specific antibacterial activity. The primary endpoint was MRSA colonization at 6-months post-randomization; secondary endpoints were time to MRSA clearance, subsequent MRSA infections/SSTI, and predictors for MRSA clearance at the 6-month time point. RESULTS: Forty-nine (9%) HIV-infected persons were MRSA colonized and randomized. Among those with 6-month colonization data (80% of those randomized), 67% were negative for MRSA colonization in both groups (p = 1.0). Analyses accounting for missing 6-month data showed no significant differences could have been achieved. In the multivariate adjusted models, randomization group was not associated with 6-month MRSA clearance. The median time to MRSA clearance was similar in the treatment vs. placebo groups (1.4 vs. 1.8 months, p = 0.35). There was no difference on subsequent development of MRSA infections/SSTI (p = 0.89). In a multivariable model, treatment group, demographics, and HIV-specific factors were not predictive of MRSA clearance at the 6-month time point. CONCLUSION: A one-week decolonization procedure had no effect on MRSA colonization at the 6-month time point or subsequent infection rates among community-dwelling HIV-infected persons. More aggressive or novel interventions may be needed to reduce the burden of MRSA in this population. TRIAL REGISTRATION: ClinicalTrials.gov NCT00631566.

ABSTRACT

Malaria in Jamaica is a real, but uncommon entity and poses a health risk to our Department of Defense personnel, which should not be overlooked in returning travelers. Malaria in Jamaica was actually considered eradicated in the 1960s, but there has been a reemergence attributed to the combination of Haitian nationals as well as endemic Anopheles mosquitoes in the Kingston area. Our facility recently admitted a 33-year-old Marine who had two Emergency Department visits before being evaluated for malaria. He had returned from Kingston 14 days before presentation, which included fever, night sweats, and headache followed by a period of malaise prior to the next paroxysm. He was found to have a 1.5% parasitemia with Malaria falciparum that borders on severe malaria. Fortunately, he was treated effectively with atovaquone/proguanil and had a favorable outcome. The Center for Disease Control acknowledges that malaria is present in Jamaica, but only recommends mosquito avoidance without prophylaxis. This case emphasizes the need to consider malaria in differential diagnosis in Jamaica as well as in any returning travelers with fever because of broad global travel.

ABSTRACT

BACKGROUND: Understanding the impact of hepatitis B virus (HBV) coinfection on HIV outcomes in the highly active antiretroviral therapy (HAART) era continues to be a critical priority given the high prevalence of coinfection and the potential for impaired immunologic, virologic, and clinical recovery. METHODS: Participants from the US Military HIV Natural History Study with an HIV diagnosis on HAART and serologically confirmed HBV infection status at HAART initiation (HI) were classified into 4 HBV infection (HB) groups. HIV virologic, immunologic, and clinical outcomes were evaluated by HB status. RESULTS: Of 2536 HIV-positive HAART recipients, with HBV testing results available to determine HB status in the HI window, HB status at HI was classified as HB negative (n = 1505; 66%), resolved HB (n = 518; 23%), isolated hepatitis B core antigen (n = 139; 6%), or chronic HB (n = 131; 6%). HIV virologic suppression and failure at 6 months or 1 year were not significantly different by HB status. A significantly faster rate of increase in CD4 cell count during the period between 4 and 12 years was observed for chronic HB relative to HB negative. Chronic and resolved HB were associated with an increased risk of AIDS/death compared with HB-negative individuals (chronic HB-hazard ratio = 1.68, 95% confidence interval: 1.05 to 2.68; resolved HB-hazard ratio = 1.61, 95% confidence interval: 1.15 to 2.25). CONCLUSIONS: HB status did not have a significant impact on HIV virologic outcomes, however, CD4 cell count reconstitution after HI and the risk of an AIDS event or death after HI may be associated with HB status.

ABSTRACT

BACKGROUND: The Veterans Aging Cohort Study (VACS) index is a weighted combination of age and 8 clinical variables. It has been well correlated with all-cause mortality among HIV-infected patients. The US Military HIV Natural History Study (NHS) cohort provides a different validation population profile, being younger and healthier. A significant portion of the US HIV population is similarly composed; so, evaluation of the VACS index in this population is of great interest. METHODS: NHS subjects have medical history and laboratory data collected at 6-month visits. We performed an external validation of the VACS index in the NHS evaluating correlation, discrimination, and calibration for all-cause mortality after highly active antiretroviral therapy initiation (HI). We then tested whether combining longitudinal VACS index values at different time points improves prediction of mortality. RESULTS: The VACS index at 1 year after HI was well correlated with all-cause mortality (Harrell c statistic 0.78), provided good discrimination (log-rank P < 0.05), and was marginally well calibrated using Brier score. Accounting for VACS index at HI and 6 months after HI significantly improved a standard model, including only the VACS index at 1 year after HI (net reclassification improvement = 25.2%, 95% CI: 10.9% to 48.9%). CONCLUSIONS: The VACS index was well correlated and provided good discrimination with respect to all-cause mortality among highly active antiretroviral therapy initiating subjects in the NHS. Moderate overprediction of mortality in this young, healthy population suggests minor recalibration that could improve fit among similar patients. Considering VACS index at HI and 6 months improved outcome prediction and allowed earlier risk assessment.

ABSTRACT

OBJECTIVES: Neisseria gonorrhoeae (GC) and Chlamydia trachomatis (CT) can facilitate transmission of HIV. Men who have sex with men (MSM) may harbour infections at genital and extragenital sites. Data regarding extragenital GC and CT infections in military populations are lacking. We examined the prevalence and factors associated with asymptomatic GC and CT infection among this category of HIV-infected military personnel. DESIGN: Cross-sectional cohort study (pilot). SETTING: Infectious diseases clinic at a single military treatment facility in San Diego, CA. PARTICIPANTS: Ninety-nine HIV-positive men were evaluated-79% men who had sex with men, mean age 31 years, 36% black and 33% married. INCLUSION CRITERIA: male, HIV-infected, Department of Defense beneficiary. EXCLUSION CRITERIA: any symptom related to the urethra, pharynx or rectum. PRIMARY OUTCOME MEASURES: GC and CT screening results. RESULTS: Twenty-four per cent were infected with either GC or CT. Rectal swabs were positive in 18% for CT and 3% for GC; pharynx swabs were positive in 8% for GC and 2% for CT. Only one infection was detected in the urine (GC). Anal sex (p=0.04), male partner (OR 7.02, p=0.04) and sex at least once weekly (OR 3.28, p=0.04) were associated with infection. Associated demographics included age <35 years (OR 6.27, p=0.02), non-Caucasian ethnicity (p=0.03), <3 years since HIV diagnosis (OR 2.75, p=0.04) and previous sexually transmitted infection (STI) (OR 5.10, p=0.001). CONCLUSIONS: We found a high prevalence of extragenital GC/CT infection among HIV-infected military men. Only one infection was detected in the urine, signalling the need for aggressive three-site screening of MSM. Clinicians should be aware of the high prevalence in order to enhance health through comprehensive STI screening practices.

ABSTRACT

BACKGROUND: Herpes simplex virus (HSV) is an unusual cause of postpartum endometritis. We describe a rare case of primary disseminated maternal HSV in the postpartum period associated with endometritis. CASE: A previously healthy patient developed fundal tenderness and postpartum fevers after an uncomplicated vaginal delivery. Despite traditional broad-spectrum antimicrobial therapy, she had persistent fevers and systemic symptoms. Concurrently, her neonate developed fevers and a nonvesicular rash, with viral cultures ultimately returning positive for HSV. The patient developed active pharyngeal and genital herpetic lesions and was diagnosed with HSV endometritis and disseminated HSV. Symptoms and fevers in both the mother and neonate responded to antiviral therapy. CONCLUSION: Herpes simplex virus endometritis should be included in the differential diagnosis for postpartum fevers and fundal tenderness that are unresponsive to broad-spectrum antimicrobial treatment.

ABSTRACT

It is estimated that there are approximately 76 million illnesses, 325,000 hospitalizations, and 5,200 deaths in the US each year attributed to foodborne outbreaks with a total cost of 10-83 billion US dollars a year. While the rates of foodborne disease have remained relatively constant over the last few years, there have been large outbreaks associated with either a component of commercially prepared food or outbreaks that span between states or even countries. With the world population expecting fresh produce year round, organic produce, and exotic foods, these global outbreaks have the potential to increase in number and severity. There needs to be a means to both rapidly identify these outbreaks, screen our food supply, as well as prevent these outbreaks. This article will discuss the global nature of this problem associated with our food and water supply as well as explain potential ways to solve this international problem.

ABSTRACT

OBJECTIVE: To test our hypothesis that a targeted rectal screening protocol before transrectal ultrasound (TRUS)-guided biopsy would potentiate streamlined prophylaxis, thereby reducing postbiopsy infectious rates while minimizing unnecessary broad-spectrum antibiotic use. To this end, we instituted preprocedure rectal cultures in an effort to identify fluoroquinolone (FQ)- resistant flora using selective media to optimally direct targeted prophylactic antibiotic administration. The inexorably increasing prevalence of multidrug-resistant microorganisms, notably extended spectrum beta lactamase (ESBL)-producing and FQ-resistant Enterobacteriaceae has increased the post-TRUS prostatic biopsy infection rates, including life-threatening sepsis. METHODS: A total of 235 rectal swabs were obtained and plated directly onto MacConkey agar plates containing 10-µg/mL ciprofloxacin. Following the screening procedure, antimicrobial susceptibility results were used to develop a customized antibiotic prophylaxis regimen to be administered before biopsy. Following the biopsy procedure, the patients were seen in follow-up within 7 days, and information was gathered on potential adverse effects, clinical appointments for infections, and potential antibiotics received. RESULTS: Thirty-two-patients (14%) had FQ-resistant isolates (most Escherichia coli), and 3 (1.3%) were ESBL-producing isolates. There were no infectious complications identified in this period, (compared with 3 septic complications among 103 biopsies in the 4 months preceding the study). CONCLUSION: Rectal cultures obtained before TRUS biopsy, using selective media to identify FQ-resistant Enterobacteriaceae, facilitate targeted antibiotic prophylaxis, and appear to be highly efficacious in reducing infectious complications.

OBJECTIVES: To investigate the epidemiology and risk factors of gonorrhoea (GC) or chlamydia (CT) coinfection in an HIV-positive US military cohort, focusing on the time after participants' knowledge of HIV diagnosis. METHODS: The authors analysed data from 4461 participants enrolled in the U.S. Military Natural History Study cohort for GC or CT infection ≥6 months after their HIV-positive test. RESULTS: During a mean follow-up of 7.08 years, 482 (11%) participants acquired a GC or CT infection. Of these, 283 (6%) acquired a GC infection, 278 (6%) acquired a CT infection and 123 (3%) had multiple GC or CT infections during follow-up. Risk of GC or CT infection was significantly greater in those younger, male, African-American and with a history of GC or CT infection. CONCLUSIONS: Frequent GC and CT diagnoses observed among members of this HIV-positive cohort indicate substantial ongoing risk behaviours that raise concerns for HIV transmission and underscore the need for continued screening to help identify and treat these sexually transmitted infections in this population.

ABSTRACT

We present an interesting case of a 27-year-old male with coccidioidal meningitis who developed permanent erectile dysfunction (ED) and lower urinary tract symptoms 3 months after initiation of therapy. The patient presented to the urology clinic with a complaint of a weak stream, urinary urgency and frequency, as well as enuresis which were only moderately controlled with anti-cholinergics. His ED responded well to phosphodiesterase-5 inhibitors. After an extensive review of the literature, this is the first report of delayed presentation of ED and lower urinary tract symptoms secondary to coccidioidal meningitis.

ABSTRACT

Hand infections are commonly seen by orthopedic surgeons as well as emergency room and primary care physicians. Identifying the cause of the infection and initiating prompt and appropriate medical or surgical treatment can prevent substantial morbidity. The most common bacteria implicated in hand infections remain Staphylococcus aureus and Streptococcus species. Methicillin-resistant S aureus infections have become prevalent and represent a difficult problem best treated with empiric antibiotic therapy until the organism can be confirmed. Other organisms can be involved in specific situations that will be reviewed. Types of infections include cellulitis, superficial abscesses, deep abscesses, septic arthritis, and osteomyelitis. In recent years, treatment of these infections has become challenging owing to increased virulence of some organisms and drug resistance. Treatment involves a combination of proper antimicrobial therapy, immobilization, edema control, and adequate surgical therapy. Best practice management requires use of appropriate diagnostic tools, understanding by the surgeon of the unique and complex anatomy of the hand, and proper antibiotic selection in consultation with infectious disease specialists.

ABSTRACT

Protective immunity and host resistance to coccidioidomycosis require a robust cell-mediated immunity with adequate production of Th1 cytokines including interleukin-12, and IFN-γ and appropriate regulation and coordinated functionality of Th1/Th2 responses and IL-12/IFN-γ cytokine axes. IFN-γ augments the anti-fungal activity of effector immune cells against a variety of fungi. Numerous animal models have demonstrated the potential efficacy of adjunctive IFN-γ in treatment of invasive mycoses. Yet, despite these promising data, a paucity of literature documents efficacious adjunctive IFN-γ administration in refractory coccidioidomycosis. We present two cases of refractory disease occurring at our institution who responded to adjunctive IFN-γ.
