This study examined the relationship of post-traumatic and depressive symptom severity with measures of health-related quality of life (HRQOL), and health care utilization in a sample of 503 HIV-infected men who have sex with men (MSM) recruited in their primary HIV care setting. Participants completed computer assisted assessments of mood and anxiety, HRQOL, and HIV treatment. Peripheral blood CD4 (T helper) lymphocyte count, plasma HIV RNA concentration, and number of medical appointments were extracted from an electronic medical record. Controlling for demographics, disease stage, and antiretroviral medication, post-traumatic stress and depression symptoms accounted for significant variation in general health estimates, and in pain, role, and work-related impairment. Additionally, in multivariable models, post-traumatic stress and depression severity accounted for significant variation in health care utilization whereas symptoms and indices of HIV disease progression did not. These results extend the current research by providing evidence of the relationship between post-traumatic stress and depression symptom severity with measures of functional impairment and health care utilization in a relatively healthy, urban cohort of HIV-infected MSM.

We evaluated pain frequency and severity in 339 women enrolled in the Women's Interagency HIV Study (WIHS). Among these, 63% were 39 years of age or younger, 17% were white, 54% African American, and 29% Hispanic; 32% did not complete high school; 58% had a CD4 less than 200; 65% had clinical AIDS; 60% were on highly active antiretroviral therapy (HAART); and 32% had a viral load of 50,000 or more. Data were collected between 1996 and 1998. Within the past 6 months 190 (56%) women experienced pain 6 or more days and 168 (50%) women indicated pain severity scores of 4 or 5 (5-point scale). Pain frequency and pain severity were not associated with age, education, ethnicity, current therapy, or location of the WIHS site. Pain frequency and severity were related to lower CD4 count, higher depression, with a history and longer duration of smoking and use of marijuana. Severity was associated with a history of crack/cocaine or heroin use or with injection drug use as the transmission category. In the multivariate models, pain severity was related to CD4 count and depression and to current tobacco use but not to crack, cocaine, heroin, or marijuana use. Pain frequency was related to depression and to former tobacco, crack, cocaine, heroin, or marijuana use but not to current use. The long-term effects of tobacco use may be to increase pain experience but women may also smoke tobacco or use other substances to give mild pain relief. Pain is frequent and often severe among women with HIV requiring medical management.

We are evaluating the use of electroporation (EP) to deliver a novel DNA vaccine, p.DOM-PSMA(27). This vaccine encodes a domain (DOM) of fragment C of tetanus toxin to induce CD4(+) T cell help, fused to a tumor-derived epitope from prostate-specific membrane antigen (PSMA) for use in HLA-A2(+) patients with recurrent prostate cancer. We report on safety and tolerability and on antibody response to DOM as a first indication of the effect of EP in patients. In this open label phase I/II, two-arm, dose escalation trial DNA was delivered either by intramuscular injection or by intramuscular injection followed by EP (DNA+EP), with five patients per dose level. Three vaccinations were given at 0, 4, and 8 weeks,with booster doses at 24 and 48 weeks; here we allowed crossover between study arms if supported by the safety and immunological data. In the 20 patients in the first two dose cohorts we observed that beyond brief and acceptable pain at the injection site, EP did not appear to add toxicity to the vaccination. We evaluated humoral responses to DOM. Low anti-DOM IgG antibody responses were observed after intramuscular injection of DNA without EP (at week 12: mean 1.7- vs. 24.5-fold increase over baseline with DNA+EP). These could be boosted by delivery of DNA+EP at later time points. Delivery of DNA+EP at all five vaccinations yielded the highest levels of anti-DOM antibody. Responses persisted to 18 months of follow-up. These data establish EP as a potent method for stimulating humoral responses induced by DNA vaccination in humans.

Postherpetic neuralgia (PHN) is a severe sequela of herpes zoster (HZ). Until now, only age and pain severity were considered predisposing factors for the development of PHN. We evaluated 49 patients with acute phase HZ, 10 of whom developed PHN (Group A) and 39 of whom did not develop PHN (Group B). Twenty-five healthy volunteers similar in age and gender distribution to the study group were recruited as controls (Group C). Numbers of serum CD3(+) (pan-T lymphocytes), CD4(+) (helper/inducer), and CD8(+) (suppressor/cytotoxic) lymphocytes were decreased significantly in Groups A and B relative to the control group, but there were no statistical differences between Groups A and B. Interleukin (IL)-1beta, IL-6, tumor necrosis factor (TNF)-alpha, IL-8, and IL-10 were significantly elevated in Groups A and B relative to Group C. IL-6 was significantly higher in Group A than in Group B, and was significantly positively correlated with pain severity scored on a visual analog scale. Therefore, we suggest that the inflammatory response, especially that of IL-6, in the acute phase of HZ may be associated with hyperalgesia and the development of PHN.

Experimental autoimmune neuritis (EAN) is a helper T cell-mediated autoimmune demyelinating inflammatory disease of the peripheral nervous system and serves as the animal model for human inflammatory demyelinating polyneuropathies. Compound A, a plant-derived phenyl aziridine precursor, was reported to activate glucocorticoid receptors to exert transrepression but not transactivation properties. In this study, we investigated the effects of Compound A in EAN rats. Compound A greatly suppressed paraparesis in EAN, even when administrated after the appearance of the first neurological signs. Accumulation of macrophages and lymphocytes, demyelination, and mRNA levels of inflammatory molecules in sciatic nerves of EAN were greatly attenuated by Compound A. In addition, Compound A inhibited progression of neuropathic pain and repressed microglia but not astrocyte activation and IL-1beta and TNF-alpha up-regulation in EAN spinal cords. In EAN sciatic nerves, Compound A treatment increased numbers of anti-inflammatory M2 macrophages. Furthermore, Compound A induced the switch of macrophages from inflammatory M1 type to anti-inflammatory M2 type in vitro. In lymph nodes of EAN rats, Compound A depressed Th1 and Th17 cytokines, but increased Th2 cytokine and Foxp3 expression. An increase of Foxp3(+)/CD4(+) regulatory T cells was seen in peripheral blood of EAN rats following Compound A treatment. In addition, Compound A did not cause a hyperglycemia effect in EAN rats as compared with the immunosuppressive steroid prednisolone. Therefore, our data demonstrated that Compound A could effectively suppress EAN with reduced side effects by attenuating inflammation, suggesting that Compound A could be a potent candidate for treatment of autoimmune neuropathies.

Personal characteristics that interact with both HIV diagnosis and its medical management can influence symptom experience. Little is known about how symptoms in populations with chronic illness vary by age, sex, or socioeconomic factors. As part of an ongoing prospective longitudinal study, this report describes symptoms experienced by 317 men and women living with HIV/AIDS. Participants were recruited at HIV clinics and community sites in the San Francisco Bay Area. Measures included the most recent CD4 cell count and viral load from the medical record, demographic and treatment variables, and the 32-item Memorial Symptom Assessment Scale to estimate prevalence, severity, and distress of each symptom and global symptom burden. The median number of symptoms was nine, and symptoms experienced by more than half the sample population included lack of energy (65%), drowsiness (57%), difficulty sleeping (56%), and pain (55%). Global symptom burden was unrelated to age or CD4 cell count. Those with an AIDS diagnosis had significantly higher symptom burden scores, as did those currently receiving antiretroviral therapy. African Americans reported fewer symptoms than Caucasians or Mixed/Other race, and women reported more symptom burden after controlling for AIDS diagnosis and race. Because high symptom burden is more likely to precipitate self-care strategies that may potentially be ineffective, strategies for symptom management would be better guided by tailored interventions from health care providers.

Immune reconstitution inflammatory syndrome (IRIS) describes the initial clinical deterioration some patients manifest upon initiation of effective antiretroviral therapy (ART) for HIV infection. In this report we describe a case of IRIS manifesting as polyarticular gout, a previously unreported rheumatological manifestation of IRIS. A 53-year-old HIV-infected man with a history of intermittent attacks of gout and an initial CD4 count of 112 cells/microL and a viral load of >100,000 copies/mL presented to our institution with severe, refractory, polyarticular gout approximately 4 weeks after initiating ART. At this point, the patient demonstrated significant gains in his CD4 counts (103 cells/microL) and a greater than 3 log decline in his HIV-1- viral load. This episode was prolonged lasting for approximately 10 weeks and required hospitalization for the management of pain and control of inflammation. The temporal associations of this attack with the initiation of ART and the observed immunologic reconstitution make IRIS a clinical possibility.Monosodium urate crystals through their interactions with interleukin 1- beta, and neutrophilic synovitis play a critical role in the pathophysiology of gout. Defects in both neutrophil and macrophage function and imbalances in the cytokine milieu are documented in HIV infected patients. The introduction of ART results in restoration of neutrophil and macrophage function, declines in levels of the anti-inflammatory cytokine IL-10, and increases in levels of proinflammatory cytokines including IL-1 beta, which may provide the necessary milieu for the precipitation of attacks of severe polyarticular gout in the context of ART initiation.

A 60-year-old woman complained of chest and axillary pain, which had initially appeared three months previously and had recently become worse. A chest CT revealed hilus-mediastinal lymphadenopathy. Because an increased serum ACE level was observed, sarcoidosis was suspected and further investigations performed. The number of lymphocytes had also increased in the BALF (67%) and the CD4/CD8 ratio was significantly higher than normal (7.5). A histological examination of a specimen obtained by TBLB revealed epithelioid cell granuloma. FDG-PET CT showed an increased uptake in the hilus-mediastinal lymph node and thoracic spinal cord. An abnormal image suggesting extradural epithelioid cell granuloma was identified at the C7-Th8 levels of the thoracic spinal cord by MRI. The pain was thus suspected to have been caused by compression of the spinal cord due to the presence of the epithelioid cell granuloma. Oral administration of prednisolone (50mg/day) improved her symptoms as well as the findings on both FDG-PET CT and MRI.

The purpose was to estimate the frequency, characteristics, and risk factors of HIV-associated distal sensory polyneuropathy (DSP) among South Africans who attend an urban community-based clinic. In a cross-sectional study, neuropathy status was determined in 598 HIV-infected adults using validated tools (Brief Peripheral Neuropathy Screen and a modified version of the Total Neuropathy Score) to categorize subjects as DSP versus no DSP. Symptomatic DSP (SDSP) required the presence of at least two neuropathic signs together with symptoms. Clinical, anthropometric, and laboratory evaluations were prospectively performed. CD4 counts, antiretroviral therapy (ART), and questionnaires regarding previous tuberculosis (TB) and alcohol exposure were collected retrospectively. Approximately half (49%) of the study population were diagnosed with DSP, and 30% of the study population were diagnosed with SDSP. In multivariate analyses the odds ratio (OR) (95% confidence interval) of DSP were independently associated with ART use (OR 1.7, 1.0-2.9), age (per 10 year increment) (OR 1.7, 1.4-2.2), and prior TB (OR 2.0, 1.3-3.0). Pain or paresthesias were reported as moderately severe by 70% of those with SDSP. Stavudine use was significantly associated with DSP. DSP is a clinically significant problem in urban HIV-infected Africans. Our findings raise the possibility that the incidence of DSP may be reduced with avoidance of stavudine-containing regimens in older subjects, especially with a history of prior TB infection.

Isolated cryptococcal osteomyelitis, in an immunocompetent, is rare and only a few cases have been reported in literature. We present the case of a 30-year-old man presented with pain on the left side of chest with fever and gradually increasing swelling in left lateral lower aspect of chest. Investigation revealed a lytic lesion in the anterior end of left 6(th) rib with normal CD4 count. He was tested negative for HIV antigen. Excision of the sixth rib, morphologically revealed cryptococcal osteomyelitis and the patient was given anti-fungal treatment for six months.
