Random-effects model: A statistical model in which both within-study sampling error (variance) and between-studies variation are included in the assessment of the uncertainty (confidence interval) of the results of a meta-analysis 100 mg kamagra oral jelly otc. When there is heterogeneity among the results of the included studies beyond chance order 100mg kamagra oral jelly mastercard, random-effects models will give wider confidence intervals than fixed-effect models. Randomization: The process by which study participants are allocated to treatment groups in a trial. Adequate (that is, unbiased) methods of randomization include computer generated schedules and random-numbers tables. Randomized controlled trial: A trial in which two or more interventions are compared through random allocation of participants. Regression analysis: A statistical modeling technique used to estimate or predict the influence of one or more independent variables on a dependent variable, for example, the effect of age, sex, or confounding disease on the effectiveness of an intervention. Relative risk: The ratio of risks in two groups; same as a risk ratio. Retrospective study: A study in which the outcomes have occurred prior to study entry. Risk: A way of expressing the chance that something will happen. It is a measure of the association between exposure to something and what happens (the outcome). Risk is the same as probability, but it usually is used to describe the probability of an adverse event. It is the rate of events (such as breast cancer) in the total population of people who could have the event (such as women of a certain age). Risk difference: The difference in size of risk between two groups. In intervention studies, it is the ratio of the risk in the intervention group to the risk in the control group. A risk ratio of 1 indicates no difference between comparison groups. For undesirable outcomes, a risk ratio that is <1 indicates that the intervention was effective in reducing the risk of that outcome. Antihistamines Page 53 of 72 Final Report Update 2 Drug Effectiveness Review Project Run-in period: Run in period: A period before randomization when participants are monitored but receive no treatment (or they sometimes all receive one of the study treatments, possibly in a blind fashion). The data from this stage of a trial are only occasionally of value but can serve a valuable role in screening out ineligible or non-compliant participants, in ensuring that participants are in a stable condition, and in providing baseline observations. A run-in period is sometimes called a washout period if treatments that participants were using before entering the trial are discontinued. This term (or the term ‘‘safe’’) should not be used when evidence on harms is simply absent or is insufficient. Sample size: The number of people included in a study. In research reports, sample size is usually expressed as "n. Larger sample sizes also increase the chance that rare events (such as adverse effects of drugs) will be detected. Sensitivity analysis: An analysis used to determine how sensitive the results of a study or systematic review are to changes in how it was done. Sensitivity analyses are used to assess how robust the results are to uncertain decisions or assumptions about the data and the methods that were used. Side effect: Any unintended effect of an intervention. Side effects are most commonly associated with pharmaceutical products, in which case they are related to the pharmacological properties of the drug at doses normally used for therapeutic purposes in humans. Standard deviation (SD): A measure of the spread or dispersion of a set of observations, calculated as the average difference from the mean value in the sample. Standard error (SE): A measure of the variation in the sample statistic over all possible samples of the same size. The standard error decreases as the sample size increases. Standard treatment: The treatment or procedure that is most commonly used to treat a disease or condition. In clinical trials, new or experimental treatments sometimes are compared to standard treatments to measure whether the new treatment is better. Statistically significant: A result that is unlikely to have happened by chance. Study: A research process in which information is recorded for a group of people. The data are used to answer questions about a health care problem. Study population: The group of people participating in a clinical research study.

Immune reconstitution is the best protection against relapses or other OIs kamagra oral jelly 100 mg with mastercard. For patients with OIs such as PML or cryptosporidiosis order kamagra oral jelly 100mg with amex, which have no specific therapy, starting ART is the best hope. Especially in these cases there is no time to waste. ART should also be started rapidly in cases of PCP or toxoplasmosis. Table 1: Important cut-offs for CD4 T cells, above which particular AIDS-related illnesses are unlikely. However, exceptions are always possible No cut-off Kaposi’s sarcoma, pulmonary tuberculosis, HZV, bacterial pneumonia, NHL <250/μl PCP, esophageal candidiasis, PML, HSV <100/μl Cerebral toxoplasmosis, cryptococcosis, miliary tuberculosis, HAND <50/μl CMV retinitis, atypical mycobacteriosis Opportunistic Infections (OIs) 333 Although OI therapy is not without toxicity and there are problems regarding inter- actions, the options of antiretroviral drugs has increased, making it easier to react to these issues. In ACTG A5164, a total of 282 subjects with an acute OI (63% PCP) were randomized to initiate ART immediately or after OI treatment (Zolopa 2009). At 48 weeks significantly less mortality and AIDS-related infections occurred in the group starting ART immediately. The risk of changing ART was slightly higher in the immediate group, although not the number of adverse events, hospitalizations or cases of IRIS. ACTG A5164 provides clear arguments for immediate initiation of ART when PCP is diagnosed. However, this does not necessarly apply to all OIs (Lawn 2011). Two randomized studies in patients with cryptococcal meningitis (Makadzange 2010) and tuberculous menin- gitis (Torok 2011) showed unfavorable effects when starting ART too early (see chapter on Late Presenters). The next chapter is intended to be a practical overview and does not include clinical rarities. The literature cited refers to interesting reviews and almost exclusively to controlled studies, and when applicable, randomized studies.

In the last 20 years, there has been significant progress made in understanding this organism, especially through DNA analysis (Review: Thomas 2004). Although pneumocystis was previously classified as a protozoan, it was estab- lished in 1988 that it is in fact an unusual type of fungus (Edman 1988). In the 1990s, it was recognized that every host, whether rat, mouse, monkey or human, has its own specific pneumocysts. The Pneumocystis species that affects humans is now referred to as Pneumocystis jiroveci, and “carinii” has now been taken out of the name, although the abbrevia- tion PCP remains (Stringer 2002).
