In recent years, interest in the use of computerized neuropsychological (NP) assessment measures has increased. However, there are limited data regarding how performance on these measures relates to performance on more traditional, clinical instruments. In the present study, 82 HIV+ men, who were all believed on clinical grounds to have neurobehavioral impairment, completed a traditional NP battery (TNB) and the California Computerized Assessment Package (CalCAP, a collection of computerized reaction time tests). Summary scores based on a TNB, as well as those based on the CalCAP, demonstrated significant associations with both degree of immunosuppression (CD4 count) and detectable viral load in cerebrospinal fluid, but not with detectable viral load in plasma. Established norms on the TNB and CalCAP batteries resulted in classifying 57% and 49% of the HIV+ sample as impaired, respectively. When using the TNB as the “gold standard,” impairment classifications based on CalCAP summary scores exhibited a sensitivity of 68% and a specificity of 77%. Overall agreement on impairment classifications between batteries was low (kappa = .44). Data from this study suggest that traditional NP batteries and computerized reaction time tests do not measure the same thing, and are not interchangeable in examining HIV-related NP impairments.

Background The risk and characteristics of upper respiratory tract (URT) bacterial infections (URT-BI) among HIV (+) patients is understudied. We analyzed factors associated with its occurrence and the spectrum of pathogens among patients routinely followed at the HIV Out-Patient Clinic in Warsaw. Methods All symptomatic HIV (+) patients with available URT swab culture were included into analyses. Patients were followed from the day of registration in the clinic until first positive URT swab culture or last clinical visit. Cox proportional hazard models were used to identify factors associated with positive URT swabs culture (those with p<0.1 in univariate included into multivariable). Results In total 474 patients were included into the analyses, 166 with positive URT swab. In general 416 (87.8%) patients were male, 342 (72.1%) were infected through MSM contact, 253 (53.4%) were on antiretroviral therapy. Median follow-up time was 3.4 (1.3-5.7) years, age 35.2 (30.6-42.6) years and CD4+ count 528 (400-685) cells/μl. The most common pathogens were S. aureus (40.4%) and S. pyogenes (13.9%) (Table 1). Patients with URT-BI were more likely to be MSM (68.5% vs 78.9%; p<0.016), have detectable viral load (20.9% vs 12.0%; p<0.0001) and CD4+ cell count <500 cells/μl (55.2% vs 39.0%; p=0.003) (Table 2). In multivariate survival analyses detectable viral load (HR3.13; 95%Cl: 2.34-4.19) and MSM (1.63;1.09-2.42) were increasing, but older age (0.63;0.58-0.69, per 5 years older) and higher CD4+ count (0.90;0.85-0.95, per 100 cells/μl) decreasing the risk of URT-BI (Table 2). Conclusions URT BI are common among HIV (+) positive patients with high CD4+ count. Similarly to general population most common patogens are S. aureus and S. pyogenes. Risk factors identified in multivariate survival analysis indicate that younger MSM patients with detectable HIV viral load are at highest risk. In clinical practice this group of patients requires special attention.

BACKGROUND: HIV/AIDS-Associated Lipodystrophy Syndrome includes changes in body fat distribution, with or without metabolic changes. The loss of fat from the face, called facial lipoatrophy, is one of the most stigmatizing signs of the syndrome.OBJECTIVES:To evaluate the effect of FL treatment using polymethylmethacrylate (PMMA) implants on disease progression, assessed by viral load and CD4 cell count.METHODS: This was a prospective study of 44 patients treated from July 2009 to December 2010. Male and female patients, aged over 18 years, with clinically detectable FL and who had never been treated were included in the study. PMMA implantation was done to fill atrophic areas. Laboratory tests were conducted to measure viral load and CD4 count before and after treatment.RESULTS: Of the 44 patients, 72.72% were male and 27.27% female, mean age of 44.38 years. Before treatment, 82% of patients had undetectable viral load, which increased to 88.6% after treatment, but without statistical significance (p = 0.67). CD4 count before treatment ranged from 209 to 1293, averaging 493.97. After treatment, the average increased to 548.61. The increase in CD4 count after treatment was statistically significant with p = 0.02.CONCLUSION: The treatment of FL with PMMA implants showed a statistically significant increase in CD4 count after treatment, revealing the impact of FL treatment on disease progression. Viral load before and after treatment did not vary significantly.

Dacryocystorhinostomy (DCR) is the ‘gold standard’ treatment for nasolacrimal duct obstruction (NLDO). However, despite its recent technical advancements, complications are possible. Herein, to the best of our knowledge, we present the first reported case of delayed unilateral pneumocephalus after bilateral endoscopic DCR. An 85-year-old man with bilateral NLDO underwent endoscopic DCR with silicone intubation. After 1 month, he became lethargic and was admitted to emergency room. Brain CT demonstrated left pneumocephalus and a suspected microfistula in left orbital wall. Intravenous antibiotic therapy was started, and cerebrospinal fluid studies showed no evidence of meningitis. After 13 days of antibiotic treatment, his mental state recovered with no signs of pneumocephalus. Although DCR has high success rate and is relatively safe, surgeons should be aware of the risk, although low, of pneumocephalus, especially in elderly patients who are vulnerable to fractures and who exhibit headache or mental status changes after endoscopic DCR.

<b><i>Objectives:</i></b> The aim of present work was to assess cytomegalovirus (CMV) viremia in Iranian human immunodeficiency virus (HIV)-1-infected patients with a CD4+ count &#x3c;100 cells/mm<sup>3</sup> and to explore whether CMV DNA loads correlate with CD4+ cell counts or associated retinitis. <b><i>Methods:</i></b> This study was conducted at the AIDS research center in Iran on HIV-1-infected patients with CD4+ count &#x3c;100 cells/mm<sup>3</sup>, antiretroviral therapy-naive, aged ≥18 years with no previous history of CMV end-organ disease (CMV-EOD). <b><i>Results:</i></b> Thirty-nine of 82 patients (47.56%) had detectable CMV viral load ranging from 66 to 485,500 IU/mL. CMV viral load in patients with retinitis ranges from 352 to 2,720 IU/mL, and it was undetectable in 2 patients. No significant associations between CMV viremia and CD4+ cell count was found (<i>p</i> value = 0.31), whereas significant association of CMV viremia in HIV-infected patients with retinitis was found (<i>p</i> &#x3c; 0.02). <b><i>Conclusions:</i></b> We estimated the frequency of CMV viral load infection in Iranian HIV-1-infected patients with a CD4+ cell count &#x3c;100 mm<sup>3</sup>/mL in the largest national referral center for HIV-1 infection in Iran. Further research is required on the relevance of CMV viral load in diagnostic and prognostic value of CMV-EOD.

Abstract Background Antiretroviral therapy (ART) adherence is a primary determinant of sustained viral suppression, HIV transmission risk, disease progression and death. The World Health Organization recommends that adherence support interventions be provided to people on ART, but implementation is suboptimal. We evaluated linkage to intensive adherence counselling (IAC) for persons on ART with detectable viral load (VL). Methods Between January and December 2017, we conducted a retrospective chart review of HIV-positive persons on ART with detectable VL (> 1000 copies/ml), in Gomba district, rural Uganda. We abstracted records from eight HIV clinics; seven health center III’s (facilities which provide basic preventive and curative care and are headed by clinical officers) and a health center IV (mini-hospital headed by a medical doctor). Linkage to IAC was defined as provision of IAC to ART clients with detectable VL within three months of receipt of results at the health facility. Descriptive statistics and multivariable logistic regression analyses were used to evaluate factors associated with linkage to IAC. Results Of 4,100 HIV-positive persons on ART for at least 6 months, 411 (10%) had detectable VL. The median age was 32 years (interquartile range [IQR] 13–43) and 52% were female. The median duration on ART was 3.2 years (IQR 1.8–4.8). A total of 311 ART clients (81%) were linked to IAC. Receipt of ART at a Health Center level IV was associated with a two-fold higher odds of IAC linkage compared with Health Center level III (adjusted odds ratio [aOR] 1.78; 95% CI 1.00–3.16; p = 0.01). Age, gender, marital status and ART duration were not related to IAC linkage. Conclusions Linkage to IAC was high among persons with detectable VL in rural Uganda, with greater odds of linkage at a higher-level health facility. Strategies to optimize IAC linkage at lower-level health facilities for persons with suboptimal ART adherence are needed.
