- Enterococcus faecalis-associated lung abscess in a male adolescent- a case reportPublication . Mendes, Ana Raquel; Costa, António; Ferreira, Helena; Ferreira, CristinaBackground: Enterococci are rarely considered pulmonary pathogens; they are usually regarded as colonizers of the airway. The authors present the case of a previously healthy male adolescent, with complaints of fatigue and chest pain, who was diagnosed with Enterococcus faecalis-associated acute primary lung abscess. Case presentation: A previously healthy 17-year old boy was admitted to the pediatric ward due to a one-week history of fatigue, inspiratory left side chest pain, dry cough and nasal obstruction. On admission at the emergency department, he was afebrile, with no signs of respiratory distress, but with diminished breath sounds on the left side. A chest x-ray showed a round opacity on the posterior basal segment of the left lower lobe; he was discharged with oral amoxicillin 1000 mg three times a day with the diagnosis of community-acquired pneumonia. Due to the worsening of the productive cough with purulent stinking sputum he was re-evaluated after 4 days. Laboratory studies showed a leukocyte count of 15200/uL and a c-reactive protein of 172 mg/l. The chest computed tomography scan was suggestive of a consolidation of the left lower lobe base and a central abscess. An intravenous course of ceftriaxone and clindamycin was initiated, with a favourable clinical evolution. The bronchofibroscopy performed on day four after his admission revealed the presence of a tracheal bronchus and numerous purulent secretions. Culture examination of bronchoalveolar lavage fluid samples was positive (> 10^5) for Enterococcus faecalis. No complications were registered during his stay in the pediatric ward. He was discharged after a 14-day course of intravenous ceftriaxone and clindamycin, with the recommendation to complete a four-week course of oral amoxicillin/clavulanic acid. On his reevaluation 4 weeks after his discharge, he was asymptomatic. Conclusion: This case report highlights the importance of considering Enterococcus faecalis as an etiologic agent in cases of non-resolving or complicated cases of pneumonia, such as lung abscesses, even in young patients with no comorbidities or risk factors.
- Long-term trends in mortality and AIDS-defining events after combination ART initiation among children and adolescents with perinatal HIV infection in 17 middle- and high-income countries in Europe and Thailand: A cohort studyPublication . Judd, A.; Chappell, E.; Turkova, A.; Le Coeur, S.; Noguera-Julian, A.; Goetghebuer, T.; Doerholt, K.; Galli, L.; Pajkrt, D.; Marques, L.; Collins, I.; Gibb, D.; González-Tome, M.; Navarro, M.; Warszawski, J.; Königs, C.; Spoulou, V.; Prata, F.; Chiappini, E.; Naver, L.; Giaquinto, C.; Thorne, C.; Marczynska, M.; Okhonskaia, L.; Posfay-Barbe, K.; Ounchanum, P.; Techakunakorn, P.; Kiseleva, G.; Malyuta, R.; Volokha, A.; Ene, L.; Goodall, R.Background: Published estimates of mortality and progression to AIDS as children with HIV approach adulthood are limited. We describe rates and risk factors for death and AIDS-defining events in children and adolescents after initiation of combination antiretroviral therapy (cART) in 17 middle- and high-income countries, including some in Western and Central Europe (W&CE), Eastern Europe (Russia and Ukraine), and Thailand. Methods and findings: Children with perinatal HIV aged <18 years initiating cART were followed until their 21st birthday, transfer to adult care, death, loss to follow-up, or last visit up until 31 December 2013. Rates of death and first AIDS-defining events were calculated. Baseline and time-updated risk factors for early/late (≤/>6 months of cART) death and progression to AIDS were assessed. Of 3,526 children included, 32% were from the United Kingdom or Ireland, 30% from elsewhere in W&CE, 18% from Russia or Ukraine, and 20% from Thailand. At cART initiation, median age was 5.2 (IQR 1.4-9.3) years; 35% of children aged <5 years had a CD4 lymphocyte percentage <15% in 1997-2003, which fell to 15% of children in 2011 onwards (p < 0.001). Similarly, 53% and 18% of children ≥5 years had a CD4 count <200 cells/mm3 in 1997-2003 and in 2011 onwards, respectively (p < 0.001). Median follow-up was 5.6 (2.9-8.7) years. Of 94 deaths and 237 first AIDS-defining events, 43 (46%) and 100 (42%) were within 6 months of initiating cART, respectively. Multivariable predictors of early death were: being in the first year of life; residence in Russia, Ukraine, or Thailand; AIDS at cART start; initiating cART on a nonnucleoside reverse transcriptase inhibitor (NNRTI)-based regimen; severe immune suppression; and low BMI-for-age z-score. Current severe immune suppression, low current BMI-for-age z-score, and current viral load >400 c/mL predicted late death. Predictors of early and late progression to AIDS were similar. Study limitations include incomplete recording of US Centers for Disease Control (CDC) disease stage B events and serious adverse events in some countries; events that were distributed over a long time period, and that we lacked power to analyse trends in patterns and causes of death over time. Conclusions: In our study, 3,526 children and adolescents with perinatal HIV infection initiated antiretroviral therapy (ART) in countries in Europe and Thailand. We observed that over 40% of deaths occurred ≤6 months after cART initiation. Greater early mortality risk in infants, as compared to older children, and in Russia, Ukraine, or Thailand as compared to W&CE, raises concern. Current severe immune suppression, being underweight, and unsuppressed viral load were associated with a higher risk of death at >6 months after initiation of cART.
