Late initiation of HAART among HIV-infected patients in Spain is frequent and related to a higher rate of virological failure but not to immigrant status.

PURPOSE: To determine whether immigrant status is associated with late initiation of highly active antiretroviral treatment (HAART) and/or poor response to antiretrovirals. METHODS: GESIDA 5808 is a multicenter, retrospective cohort study (inclusion period January 2005 through December 2006) of treatment-naïve patients initiating HAART that compares HIV-infected patients who are immigrants with Spanish-born patients. A late starter (LS) was defined as any patient starting HAART with a CD4+ lymphocyte count <200 cells/µL and/or diagnosis of an AIDS-defining illness before or at the start of therapy. The primary endpoint was time to treatment failure (TTF), defined as virological failure (VF), death, opportunistic infection, treatment discontinuation/switch (D/S), or missing patient. Secondary endpoints were time to treatment failure as observed data (TTO; censoring missing patients) and time to virological failure (TVF; censoring missing patients and D/S not due to VF). RESULTS: LS accounted for 56% of the patients. Lower educational and socioeconomic level and intravenous drug use (IVDU) were associated with categorization as LS, but immigrant status was not. Cox regression analysis (hazard ratio [HR]; 95% CI) between LS and non-LS patients showed no differences in TTF (0.97; 0.78-1.20) or TTO (1.18; 0.88-1.58), although it did reveal a difference in TVF (1.97; 1.18-3.29). CD4+ lymphocyte recovery was equivalent for both LS and non-LS patients (159 vs 173). CONCLUSIONS: In our cohort, immigrant status was not shown to be related to late initiation of HAART. Although LS patients did not have a longer TTF for any reason, TVF was significantly shorter. Despite universal free access to HAART in Spain, measures to ensure early diagnosis and treatment of HIV infection are necessary.

[Vertebral osteomyelitis: description of a series of 103 cases and identification of predictive variables of the etiological group]. / Osteomielitis vertebral: descripción de una serie de 103 casos e identificación de variables predictivas del grupo etiológico.

BACKGROUND: Vertebral osteomyelitis (VO) is an infrequent disease that requires early antibiotic treatment to prevent serious disabling sequels. The aim of our study was to identify clinical variables capable to guide the initial treatment. PATIENTS AND METHODS: Our retrospective study involved 103 patients seen during a 13 years period, mostly (94%) diagnosed by magnetic resonance imaging. Patients were classified as having brucellar (50 patients), pyogenic (29 patients), tuberculous (20 patients), and other (4 patients) spondylitis. Clinical and laboratory variables entered into a multivariate analysis to identify those independently associated with each etiologic subgroup. RESULTS: Brucellar spondylitis was associated with epidemiological exposure (LR+: 14,9; LR-: 0,02), and with a blood neutrofil percentage < or = 65% (LR+: 6,6; LR-: 0,12). The presence of an underlying chronic disease (LR+: 29,5; LR-: 0,01), an erythrocyte sedimentation rate > or = 60 mm/h (LR+: 11,3; LR-: 0,07), and the absence of constitutional symptoms (LR+: 5,2; LR-: 0,18), were independent predictors of a pyogenic spondylitis. Finally, previous exposure or tuberculous disease (LR+: 11,2; LR-: 0,06), and a delay of > or = 8 weeks in first consulting (LR+: 10,6; LR-: 0,07) were associated with tuberculous spondylitis. CONCLUSION: The combination of a few clinical and laboratory variables facilitates the differential diagnosis between pyogenic, brucellar and tuberculous vertebral osteomyelitis, allowing the choice of the initial antibiotic treatment.

Fundamento. La osteomielitis vertebral (OV) es una patología infrecuente que requiere un tratamiento antibiótico precoz para prevenir secuelas invalidantes. El objetivo de este estudio es identificar variables clínicas que permitan orientar el tratamiento inicial. Pacientes y métodos. Estudio retrospectivo de una serie de 103 casos atendidos durante un período de 13 años diagnosticados en su mayoría (94%) mediante resonancia magnética nuclear. Se clasificaron como espondilitis brucelares (50 casos), piógenas (29 casos), tuberculosas (20 casos) y otras (4 casos). Los parámetros clínicos y de laboratorio se introdujeron en un análisis multivariante para identificar aquellos que se asociaban independientemente con cada grupo etiológico. Resultados. La espondilitis brucelar se asoció a antecedentes epidemiológicos de exposición (LR+: 14,9; LR­: 0,02), y a un porcentaje de neutrófilos en sangre ≤ 65% (LR+: 6,6; LR­: 0,12). La espondilitis piógena se asoció a la presencia de enfermedad crónica de base (LR+: 29,5; LR­: 0,01), una cifra de velocidad de sedimentación globular ≥ 60 mm/h (LR+: 11,3; LR­: 0,07) y ausencia de síntomas constitucionales (astenia, anorexia, adelgazamiento) (LR+: 5,2; LR­: 0,18). La espondilitis tuberculosa se asoció a antecedentes de tuberculosis o contacto tuberculoso (LR+: 11,2; LR­: 0,06) y a un tiempo de evolución en la primera consulta ≥ 8 semanas (LR+: 10,6; LR­: 0,07). Conclusión. La combinación de unas pocas variables clínicas y de laboratorio facilita el diagnóstico diferencial entre OV piógena, brucelar y tuberculosa, permitiendo orientar el tratamiento antibiótico inicial

[Clinical trial comparing efficacy and safety of four highly active antiretroviral therapy (HAART) in antiretroviral-naive treatment with advanced HIV infection]. / Ensayo clínico comparativo de eficacia y seguridad de cuatro pautas de tratamiento antirretroviral de alta eficacia (TARGA) en pacientes naive con infección por VIH avanzada.

BACKGROUND: Comparison of efficacy and safety of four highly active antiretroviral therapy regimens (HAART) including two nucleoside analogues (NA) and a protease inhibitor (PI) in HIV positive patients with advanced infection and antiretroviral naive. PATIENTS AND METHODS: Multicenter, randomized and open labeled clinical trial in ten community hospitals of Castilla-La Mancha and Madrid. Regimen 1 contains zidovudine (AZT), lamivudine (3TC) and indinavir (IDV) regimen 2 includes AZT, 3TC and ritonavir (RTV), regimen 3 was didanosine (DDI), estavudine (D4T) and IDV, and regimen 4 included DDI, D4T and RTV. Decrease in viral load of HIV (VC) has been assessed as primary endpoint and as secondary one, the increase of the numbers of CD4 lymphocytes, percentage of disease progression, adverse reactions and adherence. Measurements were made at baseline visit and at 6, 12, 24, 36 and 48 weeks. RESULTS: A total of 98 patients with a mean baseline CD4 count of 122 x 10(6)/l (range of 5-340) and a baseline viral load of 5.1 log copies/ml were included. At 48 weeks, a mean increase of the CD4 and decrease of the viral load without significant difference between the 4 regimens (103 cells/2.62 log in regimen 1; 169 cells/2.86 log in regimen 2; 171 cells/2.56 log in regimen 3 and 141 cells/1.71 log in regimen 4) were observed in the analysis of the patients in treatment. Treatment was discontinued due to adverse reactions: 24% in regimen 1, 48% in regimen 2, 26% in regimen 3 and 32% in regimen 4, without significant difference. Analyzing by PI groups, 41% of the patients with RTV and 25% of those with IDV discontinued treatment due to adverse effects. There was withdrawal from treatment due to disease progression in 7% of the RTV patients and in 9% of IDV patients. CONCLUSIONS: In the HIV positive patients with advanced infection, efficacy between the four regimens of HAART is similar, but there is a tendency to require more withdrawal due to adverse effects in the RTV group than in those of IDV, the two used as single PI.

Introducción. Comparación de la eficacia y seguridad de cuatro pautas de terapia antirretroviral de gran actividad (TARGA) incluyendo dos análogos de nucleósidos (AN) y un inhibidor de proteasa (IP) en pacientes con el virus de la inmunodeficiencia humana (VIH) con infección avanzada y naive a antirretrovirales. Pacientes y método. Ensayo clínico, multicéntrico, randomizado y abierto en diez hospitales comunitarios de Castilla-La Mancha y Madrid. La pauta 1 contenía zidovudina (ZDV), lamivudina (3TC) e indinavir (IDV); la pauta 2 incluía ZDV, 3TC y ritonavir (RTV); la pauta 3 era didanosina (DDI), estavudina (D4T) e IDV, y la pauta 4 incluía DDI, D4T y RTV. Se ha valorado como variable principal de respuesta el descenso de la carga viral del VIH (CV), y como variables secundarias: el aumento del número de linfocitos CD4, el porcentaje de progresión de la enfermedad, las reacciones adversas y la adherencia. Las determinaciones se realizaron en la visita basal y a las 6, 12, 24, 36 y 48 semanas. Resultados. Se incluyeron 98 pacientes con una media de CD4 basal de 122 x 106/l (rango de 5-340) y una carga viral basal de 5,1 log copias/ml. A las 48 semanas, en el análisis de los pacientes en tratamiento se observó un incremento medio de los CD4 y una disminución de la carga viral sin diferencia significativa entre las 4 pautas (103 células/2,62 log en la pauta 1, 169 células/ 2,86 log en la pauta 2, 171 células/2,56 log en la pauta 3 y 141 células/1,71 log en la pauta 4). Interrumpieron el tratamiento por reacciones adversas: el 24% en la pauta 1, el 48% en la pauta 2, el 26% en la pauta 3 y el 32% en la pauta 4, sin diferencias significativas. Analizando por grupos de IP el 41% de los pacientes con RTV y el 25% de los pacientes con IDV suspendieron el tratamiento por efectos adversos. Se produjo retirada del tratamiento por progresión de la enfermedad en el 7% de los pacientes con RTV y en el 9% de los pacientes con IDV. Conclusiones. En los pacientes VIH positivos con infección avanzada la eficacia entre cuatro pautas de TARGA es similar, pero existe una tendencia a precisar mayor retirada por efectos adversos en los grupos de RTV que en los de IDV, los dos usados como IP único

Corynebacterium striatum first reported case of prosthetic valve endocarditis.

We describe the case of a prosthetic valve endocarditis in a 72-year-old woman. Corynebacterium striatum was isolated in the blood samples. This organism has been described in a few cases of native valve endocarditis, but this is the first case reported of prosthetic valve endocarditis.

Vacunaciones en el adulto

En nuestro entorno sanitario, la vacunación del adulto no recibe las mismas prioridades que la infantil. Esta situación se debe en gran parte a una falta de planificación de la vacunación y a una formación inadecuada sobre las indicaciones, beneficios y disponibilidad de la vacunación en el adulto, así como a una sobrevaloración de sus efectos secundarios y contraindicaciones (AU)

Epididymoorchitis due to Brucella mellitensis: a retrospective study of 59 patients.

Epididymoorchitis is a focal form of human brucellosis described in 2%-20% of patients with brucellosis. We assessed 59 cases of Brucella epididymoorchitis (BEO) between 1991 and 1999. The median age of patients was 34 years (range, 15-75 years). The onset of symptoms was acute in 46 patients (78%). Scrotal pain and swelling (100% of patients), fever (88%), and sweating (73%) were the most common symptoms. Brucella species was isolated from blood cultures in 41 patients (69%) and from epididymal aspiration in 4 patients. Treatment consisted of a combination of a doxycycline and an aminoglycoside (n=39) or rifampin (n=10); trimethoprim-sulfamethoxazole with rifampin (n=3); or trimethoprim-sulfamethoxazole as monotherapy (n=7). The median duration of therapy was 45 days (range, 21-90 days). The infections of 9 patients (15%) failed to respond to therapy, and 15 patients relapsed (25%). Three patients with necrotizing orchitis whose infections were unresponsive to antibiotics required an orchiectomy. In general, classical brucellosis therapy is adequate for BEO.

Azithromycin and gentamicin therapy for the treatment of humans with brucellosis.

Ten patients with brucellosis were treated with azithromycin and gentamicin to assess the treatment's safety and efficacy. Seven patients had an excellent therapeutic response at the end of therapy; however, relapse was noted in 3. When relapse was considered in combination with an initial lack of efficacy, 5 patients (50%; 95% confidence interval, 18.7%-81.3%) did not respond to therapy; these results do not favor the use of azithromycin to treat brucellosis in humans.
