Bacillary angiomatosis Bacillary angiomatosis in HIV+ patients was first described in the 1980s (Review: Maguina 2000). Bacillary angiomatosis is caused by the rickettsial species Bartonella henselae and Bartonella quintana (“Rochalimaea” until the beginning of the 1990s). While Bartonella henselae is typically associated with cats, its primary host, and cat fleas, its vector; Bartonella quintana frequently affects homeless patients and is asso- ciated with poor hygiene and social-economic conditions. Several possible reservoirs have been discussed for such cases (Gasquet 1998). In a Spanish study of 340 HIV+ patients, 22% patients reacted to one or more Bartonella antigens. Of all the studied seroprevalence factors, only age was statistically significant (Pons 2008). Reportedly, Bartonella occurs more often in North and South America than in Europe. In a study of 382 febrile HIV+ patients in San Francisco, Bartonella was found to be the causative organism in 18% (Koehler 2003). Bacillary angiomatosis remains a significant differential diagnosis in all cases with skin lesions of unknown etiology. The pseudoneoplastic, vascular skin proliferation is quite often clinically and histologically mistaken for Kaposi’s sarcoma or heman- gioma. The vascular nodules or tumors may be isolated, but are usually multiple and reminiscent of fresh Kaposi’s sarcoma, with cherry red or purple nodules. One quarter of the cases may have bone involvement with painful osteolytic foci (AP elevation). Here, the skin lesions sometimes resemble dry hyperkeratotic changes such as those seen in psoriasis. In a collection of 21 cases, 19 patients had skin, 5 bone and 4 liver involvement (Plettenberg 2000). Mani- festations in lymph nodes, muscle, CNS, eye, gingiva and gastrointestinal tract have also been reported. The gram-negative bacteria are only visible on biopsy samples stained with Warthin-Starry silver stain. If this stain method is not applied, then bacillary angiomatosis will not be found. Moreover, pathologists should be informed of the suspected diagnosis, as the Warthin-Starry silver stain is not routinely performed. Reference labs should be contacted for further diagnostic details. Treatment of bacillary angiomatosis is with erythromycin (at least four weeks with 500 mg QID) or clarithromycin. Relapses are common, which is why some physi- cians favor therapy for at least three months. Supposedly effective, doxycyclin is the 404 AIDS therapy of choice for CNS involvement. Since transmission is generally via cats, US guidelines recommend not having cats as pets. Preferably, cats should be healthy and older than one year; and scratches should be avoided.

Whether this finding can be extrapolated to comparisons of sertraline with other second- generation antidepressants remains unclear discount bactroban 5gm on-line. A British study pooled data from Prescription-Event-Monitoring (PEM) of general 227 best bactroban 5gm, 228 practitioners 6 months to 1 year after they had issued prescriptions. Included drugs were fluoxetine, fluvoxamine, paroxetine, sertraline, venlafaxine, and nefazodone. The final cohort exceeded 10,000 patients for each drug. Demographics and indications were comparable among study groups. Nausea and vomiting were the two most frequent clinical reasons for withdrawal in the first month of treatment for all drugs. Venlafaxine had the highest rate of nausea and vomiting per 1000 patient months. Like patients using paroxetine, venlafaxine patients also most frequently reported male sexual dysfunction. However, sweating, impotence, and ejaculation failure were significantly higher in the paroxetine group than in the other groups (P=0. In addition, patients using paroxetine and those using nefazodone most frequently reported drowsiness and sedation. Sertraline and fluoxetine had significantly lower rate ratios of agitation and anxiety. However, there were more reports of mania during 90 days with fluoxetine than with any other drug. The death and suicide rates did not differ significantly among study groups. Among SSRIs only, drowsiness and sedation were significantly higher in the fluvoxamine and paroxetine group than in the fluoxetine and sertraline group. Overall, the mean incidence density per 1000 patient months for SSRIs was highest for fluvoxamine (fluvoxamine 17. Suicide rates did not differ significantly among study groups. Adverse events were reported by physicians rather than patients; the nonresponse rate was 40 percent. Therefore, measurement bias, selection bias, and potential confounding may compromise these results. Three RCTs were powered primarily to detect differences in adverse events between 229 80 fluvoxamine and citalopram and fluvoxamine and paroxetine, and fluvoxamine and 67 fluoxetine. A Dutch multicenter trial was designed to assess between-group comparisons of Second-generation antidepressants 74 of 190 Final Update 5 Report Drug Effectiveness Review Project gastrointestinal side effects between citalopram (20-40 mg/d) and fluvoxamine (100-200 229 mg/d). Overall, 57 percent of patients reported adverse events. Significantly more patients in the fluvoxamine group had an excess incidence of diarrhea (+13%; P=0. However, the authors did not provide a baseline comparison of gastrointestinal illnesses between groups. The second study enrolled 60 patients to fluvoxamine (50-150 mg/d) or paroxetine (20-50 80 mg/d) for 7 weeks. Sweating was the only significantly higher adverse event: 30 percent in paroxetine patients compared with10 percent in fluvoxamine patents (P=0. The third trial assessed differences in adverse events between fluvoxamine (100-150 67 mg/d) and fluoxetine (20-80 mg/d) in 100 patients over 7 weeks. Fluoxetine-treated patients suffered under nausea significantly more often than fluvoxamine patients (42. Psychiatrists recorded adverse events at each patient visit. The WHO adverse reaction terminology was used for outcome assessment. Significantly more sertraline patients had the diagnosis of depressive disorder at baseline (P<0. Diarrhea occurred more frequently in the sertraline group than in the other SSRI groups (P<0. However, abdominal pain was reported more frequently by other SSRI users than sertraline users (P<0. No other adverse event differed significantly across groups.

Are there differences in effectiveness between NSAIDs, with or without antiulcer medication, when used in adults with chronic pain from osteoarthritis, rheumatoid arthritis, soft-tissue pain, back pain, or ankylosing spondylitis? Summary of Evidence Comparisons between oral drugs • Celecoxib 200 mg/day to 800 mg/day compared with nonselective NSAIDs o Associated with similar pain reduction effects in primarily short-term randomized controlled trials of patients with osteoarthritis, rheumatoid arthritis, soft tissue pain, and ankylosing spondylitis in 11 of 12 trials • Partially selective NSAIDs compared with nonselective NSAIDs o Partially selective NSAIDs (meloxicam, nabumetone, and etodolac) were associated with similar pain reduction effects relative to nonselective NSAIDs in short-term randomized controlled trials • Comparisons among nonselective NSAIDs o Good-quality Cochrane reviews and more recent trials found no clear differences among nonselective NSAIDs in efficacy for treating osteoarthritis of the knee or hip or for low-back pain o Evidence on the comparative efficacy of salsalate was limited to 2 randomized controlled trials that found no significant difference as compared with indomethacin. Comparisons between topical drugs • We found no trials that directly compared the effectiveness or efficacy between different topical drugs • Both diclofenac 1.

Nonsteroidal antiinflammatory drugs (NSAIDs) 18 of 72 Final Report Update 4 Drug Effectiveness Review Project Detailed Assessment Effectiveness Some trials evaluated longer-term (>6-12 months) and real-life (symptoms, clinical ulcers, functional status, myocardial infarctions, pain relief) outcomes, but none were conducted in primary care or office-based settings or used broad enrollment criteria. Efficacy: Comparisons between oral drugs Celecoxib compared with nonselective NSAIDs 22-30 Eleven of 12 randomized controlled trials of arthritis patients found no significant difference in efficacy between celecoxib and an NSAID. The single study finding a difference was a randomized controlled trial of 249 randomized patients with severe osteoarthritis of the hip requiring joint replacement surgery. A significantly greater reduction in pain on walking was found for diclofenac 50 mg 3 times daily compared with celecoxib 200 mg once daily, as measured using an 100 mm visual analog scale, both in the primary 6-week assessment (difference, 12. However, insufficient information was provided to determine if an adequate method was used to conceal the allocation sequence or whether the approach produced treatment groups that were comparable at baseline in terms of important prognostic factors. Baseline characteristics were only provided for the evaluable population (N=141), which only accounted for 60% of the modified intention-to-treat population (N=235). Consequently, this randomized controlled trial was rated poor quality and its results should be interpreted with caution. The Agency for Healthcare Research and Quality Effective Health Care Program 31 Comparative Effectiveness Review found no clear differences in efficacy between celecoxib 22, 24, 26, 29 32, 33 and nonselective NSAIDs based on results from published trials and meta-analyses of published and unpublished trials. Celecoxib and nonselective NSAIDs were associated with similar pain reduction effects (Western Ontario and McMaster Universities Osteoarthritis Index, visual analogue scale, Patient Global Assessment) in published trials of patients with 22, 24, 26, 29 34, 35 36-38 29, osteoarthritis, soft tissue pain, ankylosing spondylitis, or rheumatoid arthritis. Celecoxib 200-400 mg was associated with slightly higher rate of withdrawals than other NSAIDs due to lack of efficacy (relative risk, 1. This estimate of comparative efficacy may be the most precise available, but the validity of the findings cannot be verified as the data used in this analysis is not fully available to the 33 public. On the other hand, ibuprofen 2400 mg/day and diclofenac 150 mg/day were associated with higher rates of withdrawal due to lack of efficacy than celecoxib 800 mg/day after 52 weeks (14. Nonsteroidal antiinflammatory drugs (NSAIDs) 19 of 72 Final Report Update 4 Drug Effectiveness Review Project Partially selective NSAIDs compared with nonselective NSAIDs Partially selective NSAIDs (meloxicam, nabumetone, and etodolac) were associated with similar pain reduction effects relative to nonselective NSAIDs in short-term randomized controlled trials. In 2 of the trials, however, patients taking nonselective NSAIDs were significantly less likely to withdraw due to lack of efficacy 44, 49 than patients taking meloxicam. A systematic review of 3 short-term randomized controlled trials of nabumetone for soft tissue pain found no difference in efficacy when compared with 50 ibuprofen or naproxen. However, based on physician assessment, the same systematic review also found placebo to be as efficacious as nabumetone in reducing pain at 7 days. Etodolac and nonselective NSAIDs were generally associated with similar rates of withdrawals due to 51 52 efficacy or improvements in pain in short-term randomized controlled trials of patients with osteoarthritis of the knee and/or hip. A sustained-release form of etodolac was also associated with similar rates of pain reduction relative to diclofenac in a small trial (N=64) of patients with 53 osteoarthritis of the knee. Comparisons among nonselective NSAIDs Several recent good-quality systematic reviews by the Cochrane Collaboration found no clear 51 differences among nonselective NSAIDs in efficacy for treating osteoarthritis of the knee, 54 55 hip, or low-back pain. Results from 3 fair-quality randomized controlled trials published subsequent to the Cochrane reviews also consistently found no significant differences in efficacy 56-58 among nonselective NSAIDs when used in patients with osteoarthritis. Limited evidence from 2 trials found no difference in efficacy when salsalate 3 g daily 59 60 was compared with indomethacin 75 mg daily or diclofenac 75 mg daily. No studies comparing salsalate to other NSAIDs were identified, and salsalate was not included in any of the systematic reviews included in this report. Tenoxicam 20 mg and 40 mg, diclofenac, and indomethacin were associated with similar 61 effects on pain in a good-quality systematic review of 18 randomized controlled trials. Tenoxicam was also associated with slightly greater improvements in pain management outcomes than piroxicam according to physician global assessment (odds ratio, 1.
