Objective: To review the clinical features and current knowledge on the treatment of psychiatric symptoms and disorders in patients with human immunodeficiency virus (HIV) infection. Method: We searched the PubMed database combining HIV/AIDS with different keywords for psychiatric diagnoses and symptoms (e.g. depression, mania, anxiety, psychosis, dementia, substance abuse) and for psychopharmacological treatment. The years covered by these searches included 1980 to 2008. Results: Patients with HIV infection are at an increased risk of psychiatric illness. Major depressive disorder and subsyndromal depressive symptoms, as well as anxiety disorder and substance abuse are more prevalent among HIV infected individuals than among the general population. HIV-associated neurocognitive disorders (HAND) are common among HIV patients, and HIV-associated dementia (HAD) is a serious condition during the acquired immune deficiency syndrome (AIDS) stage of HIV disease. Secondary mania and psychosis might be the first clinical symptom of HIV dementia. The introduction of highly active anti-retroviral therapy (HAART) has resulted in significant decreases in morbidity and mortality for HIV infected patients. HAART has also decreased the incidence of HAD, but does not give complete protection from this condition. The utility of psychotropic medications in HIV patients has not been studied sufficiently as a basis for guidelines, and more controlled trials are needed. Conclusion: Psychiatric illness is common in HIV infected individuals, and underlines the importance for screening not only for cognitive impairment but also for co morbid mental disease in HIV-positive patients. Further studies of the neuropsychiatric complications during HIV disease and the use of psychotropics under these circumstances are clearly needed. A better understanding of the pathogenesis of HAD is essential to identify additional therapeutic strategies for prevention and treatment of this neurodegenerative disease. Studies are also needed for optimizing effective utilization of antiretrovirals into the CNS. Mania and psychosis secondary to HAD may be used as an indicator to initiate HAART, irrespective of CD4 count. Further research on the utility of HAART in the treatment of such acute neuropsychiatric symptoms associated with HIV infection should be initiated.

HIV infection and psychiatric illness.

The safe and effective administration of fluids and medications during the management of medical emergencies in children depends on an appropriately determined dose, based on body weight. Weight can often not be measured in these circumstances and a convenient, quick and accurate method of weight estimation is required. Most methods in current use are not accurate enough, but the newer length-based, habitus-modified (two-dimensional) systems have shown significantly higher accuracy. This meta-analysis evaluated the accuracy of weight estimation systems in children. Articles were screened for inclusion into two study arms: to determine an appropriate accuracy target for weight estimation systems; and to evaluate the accuracy of existing systems using standard meta-analysis techniques. There was no evidence found to support any specific goal of accuracy. Based on the findings of this study, a proposed minimum accuracy of 70% of estimations within 10% of actual weight (PW10 > 70%), and 95% within 20% of actual weight (PW20 > 95%) should be demonstrated by a weight estimation system before being considered to be accurate. In the meta-analysis, the two-dimensional systems performed best. The Mercy method (PW10 70.9%, PW20 95.3%), the PAWPER tape (PW10 78.0%, PW20 96.6%) and parental estimates (PW10 69.8%, PW20 87.1%) were the most accurate systems investigated, with the Broselow tape (PW10 55.6%, PW20 81.2%) achieving a lesser accuracy. Age-based estimates achieved a very low accuracy. Age- and length-based systems had a substantial difference in over- and underestimation of weight in high-income and low- and middle-income populations. A benchmark for minimum accuracy is recommended for weight estimation studies and a PW10 > 70% with PW20 > 95% is suggested. The Mercy method, the PAWPER tape and parental estimates were the most accurate weight estimation systems followed by length-based and age-based systems. The use of age-based formulas should be abandoned because of their poor accuracy.

Advanced Paediatric Life Support: The Practical Approach

Distal symmetrical poly-neuropathy (DSP) is a neurological complication associated with HIV/AIDS and stavudine (d4T) containing antiretroviral therapy. People with DSP experience pain, numbness and muscle weakness, which affect their quality of life (QOL). The purpose of this study was to establish the effect of a progressive-resisted exercise (PRE) intervention on health-related quality of life (HR-QOL) in people living with HIV/AIDS-related DSP. An assessor-blinded randomised controlled trial was conducted, with participants sourced from 10 clinics with HIV services, the family care clinic at Wilkins Hospital and 2 large hospitals in Harare, Zimbabwe. A 12-week PRE intervention was conducted twice weekly for 80 participants, while the control group with 80 participants continued with usual daily activities. The main outcome variable was HR-QOL for which we controlled for demographic and clinical measures in generalised estimating equation population-averaged models. Data were summarised and analysed using an intention to treat analysis approach using the Stata v10 program. Mean age of participants was 42.2 years (SD = 8.5). While d4T was used by 59% (n = 94), an equal proportion of the participants also had moderate to severe neuropathy. PRE was found to significantly improve HR-QOL in the intervention group based on the mean difference between the intervention group mean change and the mean change in the control group (F ratio 4.24; p = .04). This study established that PREs have positive effects on HR-QOL for people living with HIV/AIDS-related DSP.

A systematic review and meta-analysis of the accuracy of weight estimation systems used in paediatric emergency care in developing countries.

In July of 2006, the National Institute of Mental Health (NIMH) Center for Mental Health Research on AIDS (CMHRA) sponsored the second conference on the Assessment of NeuroAIDS in Africa, which was held in Arusha, Tanzania. The conference mission was to address the regional variations in epidemiology of HIV-related neurological disorders as well as the assessment and diagnosis of these disorders. Participants discussed and presented data regarding the relevance and translation of neuroAIDS assessment measures developed in resource intensive settings and the challenges of neuro-assessment in Africa, including the applicability of current tools, higher prevalence of confounding diseases, and the complexity of diverse cultural settings. The conference presentations summarized here highlight the need for further research on neuroAIDS in Africa and methods for assessing HIV-related neurological disorders.

Second assessment of NeuroAIDS in Africa

This study evaluated the performance of a new weight estimation strategy (Mercy Method) with four existing weight-estimation methods (APLS, ARC, Broselow, and Nelson) in children from Ouelessebougou, Mali. Otherwise healthy children, 2 mos to 16 yrs, were enrolled and weight, height, humeral length (HL) and mid-upper arm circumference (MUAC) obtained by trained raters. Weight estimation was performed as described for each method. Predicted weights were regressed against actual weights. Agreement between estimated and actual weight was determined using Bland-Altman plots with log-transformation. Predictive performance of each method was assessed using residual error (RE), percentage error (PE), root mean square error (RMSE), and percent predicted within 10, 20 and 30% of actual weight. 473 children (8.1 ± 4.8 yr, 25.1 ± 14.5 kg, 120.9 ± 29.5 cm) participated in this study. The Mercy Method (MM) offered the best correlation between actual and estimated weight when compared with the other methods (r2 = 0.97 vs. 0.80-0.94). The MM also demonstrated the lowest ME (0.06 vs. 0.92-4.1 kg), MPE (1.6 vs. 7.8-19.8%) and RMSE (2.6 vs. 3.0-6.7). Finally, the MM estimated weight within 20% of actual for nearly all children (97%) as opposed to the other methods for which these values ranged from 50-69%. The MM performed extremely well in Malian children with performance characteristics comparable to those observed for U.S and India and could be used in sub-Saharan African children without modification extending the utility of this weight estimation strategy.
