Auditing HIV Testing Rates across Europe: Results from the HIDES 2 Study.

European guidelines recommend the routine offer of an HIV test in patients with a number of AIDS-defining and non-AIDS conditions believed to share an association with HIV; so called indicator conditions (IC). Adherence with this guidance across Europe is not known. We audited HIV testing behaviour in patients accessing care for a number of ICs. Participating centres reviewed the case notes of either 100 patients or of all consecutive patients in one year, presenting for each of the following ICs: tuberculosis, non-Hodgkins lymphoma, anal and cervical cancer, hepatitis B and C and oesophageal candidiasis. Observed HIV-positive rates were applied by region and IC to estimate the number of HIV diagnoses potentially missed. Outcomes examined were: HIV test rate (% of total patients with IC), HIV test accepted (% of tests performed/% of tests offered) and new HIV diagnosis rate (%). There were 49 audits from 23 centres, representing 7037 patients. The median test rate across audits was 72% (IQR 32-97), lowest in Northern Europe (median 44%, IQR 22-68%) and highest in Eastern Europe (median 99%, IQR 86-100). Uptake of testing was close to 100% in all regions. The median HIV+ rate was 0.9% (IQR 0.0-4.9), with 29 audits (60.4%) having an HIV+ rate >0.1%. After adjustment, there were no differences between regions of Europe in the proportion with >0.1% testing positive (global p = 0.14). A total of 113 patients tested HIV+. Applying the observed rates of testing HIV+ within individual ICs and regions to all persons presenting with an IC suggested that 105 diagnoses were potentially missed. Testing rates in well-established HIV ICs remained low across Europe, despite high prevalence rates, reflecting missed opportunities for earlier HIV diagnosis and care. Significant numbers may have had an opportunity for HIV diagnosis if all persons included in IC audits had been tested.

Treatment of cavitary and infiltrating pulmonary tuberculosis with and without the immunomodulator Dzherelo.

An open-label, 60-day trial was conducted in 75 newly diagnosed tuberculosis (TB) patients to assess the adjunctive effect of the oral immunomodulator Dzherelo with standard anti-TB chemotherapy (ATT) consisting of izoniazid, rifampicin, pyrazinamide and streptomycin (HRZS) administered as directly observed therapy (DOT). Group 1 (n = 28) with cavitary TB and group 2 (n = 17) with infiltrating pulmonary TB received 50 drops of Dzherelo twice daily in addition to HRZS. Group 3 (n = 30), which served as a control, received ATT only. Liver damage indicators, bilirubin, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) decreased to normal levels in groups 1 and 2, but increased significantly in group 3. Kidney failure markers, urea and creatinine, normalized in Dzherelo recipients, but were unchanged or worsened in the ATT-only group. The changes in serum lactate dehydrogenase, catalase, malondialdehyde and diene conjugates suggested that Dzherelo downregulates TB-associated inflammation. The anti-inflammatory property of Dzherelo was further supported by a favourable haematology profile, reduced erythrocyte sedimentation rate and faster defervescence. Radiological recovery was significant in both Dzherelo groups, but not in the control group (p = 0.0085, p = 0.025 and p = 0.23, respectively). These findings correlated positively with sputum smear conversion and clinical findings (r = 0.94; p < 0.05). Mycobacterial clearance at day 30 was observed in 77%, 72% and 40% of patients in groups 1, 2 and 3, respectively. After 2 months sputum conversion rates in groups 1, 2 and 3 were 93%, 89% and 70%, respectively. Sixty-day treatment outcomes in groups 1, 2 and 3 as assessed by improvement in clinical features and respiratory function attained respective p-values of 0.008, 0.25 and 0.72, and 0.013, 0.48 and 0.0015. Dzherelo is thus useful as an immunotherapeutic adjunct in the management of TB.
