Tuberculous Meningitis in Adults: A Review of 160 Cases

Objective. This study aimed to evaluate epidemiological, clinical, laboratory, and neuroimaging features of 160 adult patients with tuberculous meningitis (TBM) according to “Thwaites' diagnostic index.” Methods. The subjects of this retrospective study are the patients with TBM who were followed up between years 1998 and 2009 in a tertiary referral hospital. Diagnosis of TBM was based on clinical, laboratory, and neuroimaging signs and Thwaites' diagnostic index. Results. Mycobacterium tuberculosis was isolated from CSF in 59 of 148 patients. Seventeen percent of the patients died, 71% recovered completely, and 13% recovered with neurological sequel at the end of the sixth month. Conclusions. Despite new developments in laboratory or neuroimaging techniques, the diagnosis of TBM is still based on clinical features with the help of laboratory. Early diagnosis by suspecting TBM may prevent therapy delay and may result in decrease in the mortality and morbidity

Tricuspid Endocarditis and Septic Pulmonary Embolism in an Intravenous Drug User with advanced HIV Infection

Abstract Cardiac complications are becoming increasingly important in patients with HIV infection. Right-sided endocarditis are more common in intravenous drug users (IVDU) with HIV infection. Some studies have pointed out that the clinical outcome of such patients depends on the affected valve referred to the responsible agent rather than the HIV serostatus. However, severe immunosupression and low CD 4 count are associated with increased risk of death. This report presents a case of isolated tricuspid valve endocarditis with advanced HIV infection who was also an IVDU

Immune Thrombocytopenia in a Very Elderly Patient With Covid-19

Immune thrombocytopenia (ITP) is an autoimmune disorder characterized by a decreased number of platelets and mucocutaneous bleeding. Many viruses have been identified as triggers of the autoimmune process, including human immunodeficiency virus (HIV), hepatitis C virus (HCV), Epstein-Barr virus (EBV), cytomegalovirus (CMV), parvovirus, rubella, and measles. Association with the new severe acute respiratory syndrome coronavirus, SARS-CoV-2 infection (Covid-19 infection) has been rarely reported. Here, we report the oldest case of ITP patient triggered by the novel coronavirus infection. He showed inadequate response to IVIG but responded to corticosteroids with no severe adverse events. Further studies are warranted to determine the optimal therapeutic strategies for ITP with the Covid-19 infection

Comparison of systemic immune-inflammation index (SII), early warning score (ANDC) and prognostic nutritional index (PNI) in hospitalized patients with malignancy, and their influence on mortality from COVID-19

Introduction We evaluated several biological indicators based on inflammation and/or nutritional status, such as systemic immune-inflammation index (SII), early warning score (ANDC) and prognostic nutritional index (PNI) in hospitalized COVID-19 patients with and without malignancies for a prognostic significance. Methodology This is a retrospective and observational study on 186 patients with SARS-CoV-2, who were diagnosed with COVID-19 by real-time PCR testing and hospitalized due to COVID-19 pneumonia. 75 patients had various malignancies, and the rest (111), having a similar age and comorbidity profile based on propensity score matching, had no malignancy. Results None of the measures as neutrophil to lymphocyte ratio, platelet to lymphocyte ratio, monocyte to lymphocyte ratio, SII, PNI or ANDC was found to be significantly different between two groups. Odds ratio for the mortality, OR 2.39 (%95 CI 1.80-3.16) was found to be significantly higher for the malignancy group, even though the duration of hospitalization was statistically similar for both groups. PNI was found to be significantly lower for deceased patients compared with survivors in the malignancy group. Contrarily, ANDC was found to be significantly higher for deceased patients in the malignancy group. Conclusions PNI and ANDC have independent predictive power on determining the in-hospital death in COVID-19 malignancy cases. It is suggested that ANDC seems to be a more sensitive score than SII in COVID-19 cases with malignancies

Comparison of Pneumonia Severity Indices, qCSI, 4C-Mortality Score and qSOFA in Predicting Mortality in Hospitalized Patients with COVID-19 Pneumonia

This is a retrospective and observational study on 1511 patients with SARS-CoV-2, who were diagnosed with COVID-19 by real-time PCR testing and hospitalized due to COVID-19 pneumonia. 1511 patients, 879 male (58.17%) and 632 female (41.83%) with a mean age of 60.1 ± 14.7 were included in the study. Survivors and non-survivors groups were statistically compared with respect to survival, discharge, ICU admission and in-hospital death. Although gender was not statistically significant different between two groups, 80 (60.15%) of the patients who died were male. Mean age was 72.8 ± 11.8 in non-survivors vs. 59.9 ± 14.7 in survivors (p < 0.001). Overall in-hospital mortality was found to be 8.8% (133/1511 cases), and overall ICU admission was 10.85% (164/1511 cases). The PSI/PORT score of the non-survivors group was higher than that of the survivors group (144.38 ± 28.64 versus 67.17 ± 25.63, p < 0.001). The PSI/PORT yielding the highest performance was the best predictor for in-hospital mortality, since it incorporates the factors as advanced age and comorbidity (AUROC 0.971; % 95 CI 0.961–0.981). The use of A-DROP may also be preferred as an easier alternative to PSI/PORT, which is a time-consuming evaluation although it is more comprehensive

Detection of Intestinal Parasites with Conventional and Molecular Methods in Follow-up HIV/AIDS Cases

In people living with human immunodeficiency virus (HIV), several complaints related to the gastrointestinal system, mainly diarrhea can be determined. In our study, we aimed to detect the existence of intestinal parasites with conventional methods based on microscopy and with molecular methods based on multiplex-PCR among 90 anti-retroviral treatment (ART) naive or ART adherent HIV/AIDS cases. The existence of Giardia spp., Blastocystis spp., Entamoeba histolytica, Dientamoeba spp. and Cryptosporidium spp. were searched in stool samples and the relation with the existence of these parasites and demographic/clinical data of the cases were determined. The demographic and clinical data of the participants included in the study were as follows; the average age was 34.02 +/- 9.7 years, average time of diagnosis was 2.4 +/- 1.7 years. Gender distribution was as follows; 85.6% male and 14.4% female. HIV transmission was related with heterosexual intercourse in 60%, homosexual intercourse in 33.3%, blood/blood products contact in 1.1% and with unknown routes in 5.6% of the cases. Fifty percent of the patients were in pre-ART and 50% was in on-ART state. The average CD4+ T lymphocyte count was detected as 400 cells/mm(3) and the median of viral load was 114.527 copies/ml. An overall prevalence of at least one intestinal parasitic infection was recorded as 36.7% and the prevalence of this infection due to Blastocystis spp. was 22.2%, followed by Dientamoeba spp. (13.3%), E. histo lytica (4.4%), Cryptosporidium spp. (3.3%), Giardia spp. (2.2%) and multiple parasitic infections (7.7%). The type of sexual behaviours related with the detection of intestinal parasites were statistically significant especially in homosexual intercourse (p< 0.001). The increase in CD4+ T lymphocyte counts were reversely associated (p= 0.062) and the increase in the levels of viral load were positively associated (p< 0.001) with detection rate of intestinal parasite. The detection of parasites by molecular methods was statistically significant in pre-ART participants (p= 0.002) and participants with diarrhea (p= 0.019). In the present study, the increase in the frequency of intestinal parasitic infections has shown that essential interventions are required. In all HIV/AIDS cases, routine parasitic screening should be performed by more sensitive methods to manage early and specific treatment
