青少年多囊卵巢综合征的临床、超声和生化特征及其诊断意义

青春期多囊卵巢综合征(PCOS)的诊断具有一定的临床挑战性。迄今未有报道青少年人群PCOS的患病率以及临床、超声和生化特征。为了评估PCOS的临床和生化特征在14~16岁月经初潮女孩中的普遍程度,确定内循环雄激素水平在卵泡期早期的正常范围。本研究进行了一项前瞻性群组研究,研究群组是244名未经选择的月经初潮后的女孩,平均年龄在15.2岁。从一个大的以人口为基础的出生群组(Raine队列)中招募受试者。临床高雄激素血症(HA)使用Ferriman-Gallwey评分进行量化。在卵泡期的初期(第2~第6天),本研究使用免疫法测定循环雄激素和性激素结合球蛋白,并通过经腹部超声检查来评估卵巢形态,得到了青少年女性群体卵泡期初期的雄激素的正常范围。循环游离睾酮水平的前5%和10%分别为45.6 pmol/L和34.5 pmol/L。51%的女孩报告月经不规律。临床HA是罕见的,仅观察到3.5%的女孩罹患此病。平均卵巢体积大于其他报道中成年妇女的卵巢体积,35%的女孩在经腹超声时显示有多囊卵巢形态。按照游离睾酮数值排序,取前5%作为HA。42名女孩(18.5%)符合PCOS的Rotterdam标准,11个女孩(5%)雄激素超出社会标准。本研究表明,月经不规律在青春期是常见的,不涉及临床或生化HA。卵巢体积和形态的PCOS诊断在青春期可能有局限性。     

The protective effects of C16 peptide and angiopoietin-1 compound in lipopolysaccharide-induced acute respiratory distress syndrome

C16 peptide and angiopoietin-1 (Ang-1) have been found to have anti-inflammatory activity in various inflammation-related diseases. However, their combined role in acute respiratory distress syndrome (ARDS) has not been investigated yet. The objective of this study was to investigate the effects of C16 peptide and Ang-1 in combination with lipopolysaccharide (LPS)-induced inflammatory insult in vitro and in vivo. Human pulmonary microvascular endothelial cells and human pulmonary alveolar epithelial cells were used as cell culture systems, and an ARDS rodent model was used for in vivo studies. Our results demonstrated that C16 and Ang-1 in combination significantly suppressed inflammatory cell transmigration by 33% in comparison with the vehicle alone, and decreased the lung tissue wet-to-dry lung weight ratio to a maximum of 1.53, compared to 3.55 in the vehicle group in ARDS rats. Moreover, C  +  A treatment reduced the histology injury score to 60% of the vehicle control, enhanced arterial oxygen saturation (SO₂), decreased arterial carbon dioxide partial pressure (PCO₂), and increased oxygen partial pressure (PO₂) in ARDS rats, while also improving the survival rate from 47% (7/15) to 80% (12/15) and diminishing fibrosis, necrosis, and apoptosis in lung tissue. Furthermore, when C  +  A therapy was administered 4 h following LPS injection, the treatment showed significant alleviating effects on pulmonary inflammatory cell infiltration 24 h postinsult. In conclusion, our in vitro and in vivo studies show that C16 and Ang-1 exert protective effects against LPS-induced inflammatory insult. C16 and Ang-1 hold promise as a novel agent against LPS-induced ARDS. Further studies are needed to determine the potential for C16 and Ang-1 in combination in treating inflammatory lung diseases.     

Histoplasmosis diseminada y síndrome hemofagocítico en pacientes VIH: serie de casos en un hospital peruano

BackgroundDisseminated histoplasmosis (DH) is an opportunistic fungal infection in severely immunocompromised patients with HIV infection. Haemophagocytic syndrome (HFS), which can occur in these co-infected patients when the immune response is significantly altered, is often associated with high mortality.AimsTo describe the epidemiological, clinical, analytical and microbiological characteristics, along with studying the presence of HFS, in patients with DH-HIV.MethodsA retrospective study was conducted on a case series using data from the clinical records of patients diagnosed with DH and HIV infection during the years 2014 and 2015.ResultsDH was diagnosed in 8 (1.3%) of 597 HIV patients. All patients were in stage C3, and 75% (6/8) were not receiving combined antiretroviral therapy (CART). The remaining two patients had recently begun CART (possible immune reconstitution syndrome). Five (62.5%) of the 8 patients met criteria for HFS. The most frequent clinical symptoms were lymphoproliferative and consumptive syndrome, respiratory compromise, and cytopenia. Histoplasma was isolated in lymph nodes of 75% (6/8) of the patients, in blood samples in 25% (2/8), and also in intestinal tissue in one patient. The antifungal therapy was amphotericin B deoxycholate, without adjuvants. The overall mortality was 50%.ConclusionsIn this case series, DH-HIV co-infection frequently progressed to HFS with high mortality. The clinical picture may resemble that of other systemic opportunistic infections, such as tuberculosis, or can take place simultaneously with other infections. Clinical suspicion is important in patients with severe cytopenia and lymphoproliferative and consumptive syndrome in order to establish an early diagnosis and prescribing a timely specific therapy.
