The prognosis of HIV-infected patients has dramatically improved since the advent of HAART. The immune recovery associated with HAART may result in immuno-pathological reactions and clinical deterioration when HAART is initiated in patients with tuberculosis (TB). This phenomenon is defined as immune reconstitution inflammatory syndrome (IRIS). In this review, we summarise the epidemiology, clinical presentations and management of TB-associated IRIS.

Lymphogranuloma venereum (LGV) is a sexually transmitted infection caused by L1, L2, L3 serovars of C. trachomatis (CT). Since 2003, LGV cases have been increasing in Europe. Aim of this report is to describe the LGV cases diagnosed in the largest STI center in Rome, Italy, from 2000 to 2016. This report shows that two clinically and epidemiologically different series of cases exist, and that, at present, the ano-rectal LGV represents the clinical variant occurring more frequently among men having sex with men (MSM), particularly those HIV-infected.. Ten cases of LGV were observed. Three were diagnosed in 2009 in HIV-negative heterosexuals patients that presented the classical genito-ulcerative form with lymphadenopathy. Seven cases were observed in 2015-2016 in HIV-infected MSM, that presented the rectal variant and L2b serovar infection; 4 of these had been misclassified as a chronic bowel disease. Chlamydia infection was confirmed by CT-specific PCR (ompA gene nested PCR), followed by sequence analysis to identify the serovar. All the patients were treated with doxycycline for 3 weeks, obtaining a complete response with healing of both clinical symptoms and dermatological lesions.. Our findings suggest that, in case of persistent rectal symptoms in HIV-infected MSM, LGV should be taken into account and investigated through molecular analyses, in order to achieve a correct diagnosis and management of the patients.

Non-invasive positive pressure support ventilation (NIPSV).. In patients with acute hypoxaemic (PaO2/FiO2 &Mac178;100) non hypercapnic respiratory failure (ARF) admitted to a Respiratory Inter-mediate Intensive Care Unit of a general Hospital, between January 1993 and December 1997.. In 21 selected patients (PaO2/ FiO2T0=82+/-9) NIPSV improved PaO2 in 13/21 patients (Group A) and did not improve in 8/21 patients (Group B) (PaO2/FiO2T1=154+/-25 in Group A vs PaO2/FiO2T1=106+/-7.5 in Group B, p=0.00001). Upon admission the two groups did neither significantly differ for blood gas values (PaO2/FiO2T0=84+/-9.6 in Group A vs 79.8+/-8.7 in Group B), nor for clinical status (APACHE II=19.8+/-5 in Group A vs 24.6+/-7 in Group B). Shorter duration of NIPSV in Group B patients (11.2+/-19.7 hrs vs 35.3+/-32.3 hrs in Group A, p=0.047), in spite of a rise in PEEP (9.3+/-2.3 in Group B vs 5.5+/-2.4 in Group A, p=0.003) and Pressure Support (18.7+/-1.8 in Group B vs 15+/-3.2 in Group A, p=0.004) was due to onset of conditions which required shifting from NIPSV to endotracheal intubation (ETI).. 8/21 patients were successfully treated by only NIPSV. 8/21 patients were intubated. 5/21 patients dead in RIICU; 1 month survival: 9/21 patients. Side effects: mask intolerance (3/21); skin necrosis (1/21); pneumothorax (1/21).. NIPSV may be tried in ARF patients to improve PaO2 and avoid ETI.

Technical complications and nosocomial bloodstream infections associated with short-term central venous catheterization remain a heavy burden in terms of morbidity, mortality and cost in HIV-positive subjects. Between 1994 and 1997, 327 central venous catheters (CVCs) inserted in 212 patients for a total of 5005 catheter days were investigated. Forty-two technical complications (13%) occurred in 40 patients. Logistic regression analysis revealed that a high APACHE III score was associated with development of CVC-related complications (P = 0.01). One hundred and eight of 327 CVCs (33%) were suspected as being infected. However only 61 episodes (61/327, 19%) were finally diagnosed as CVC-related sepsis. Three variables affecting the rate of CVC-related sepsis were identified: 1) administration of TPN (P = 0.01); 2) low number of circulating CD4+ cells (P = 0.04); 3) high APACHE III score (P = 0. 04). Doctors responsible for AIDS patients should carefully consider the relative risks and benefits of CVC insertion in an individual patient.

A simple polymerase chain reaction (PCR) assay for rapid identification of different species of mycobacteria was developed. This PCR is based on the use of conserved sequences to amplify the genome of several mycobacterial species. The amplification patterns obtained were specific and reproducible for the species tested. In particular, we could identify Mycobacterium tuberculosis and Mycobacterium bovis (both produced the same pattern), Mycobacterium avium, Mycobacterium kansasii, Mycobacterium xenopi, Mycobacterium chelonae, Mycobacterium peregrinum, Mycobacterium fortuitum, Mycobacterium gordonae and Mycobacterium smegmatis. Moreover, due to the numerous copies of the target sequences present in the genome, the PCR showed a very high level of sensitivity.

The epidemiological features of 37 episodes of candidemia in HIV-infected subjects were analysed in a retrospective matched case-control study conducted over an 8-year period (1990-1997). Univariate analysis identified eight risk factors that were significantly associated with candidemia (P<0.05): i) use of central venous catheters; ii) administration of total parenteral nutrition; iii) previous antifungal therapy; iv) previous therapy with glycopeptides; v) presence of oral/ esophageal candidiasis; vi) concomitant bacterial infections; vii) neutropenia; and viii) concomitant AIDS dementia complex. Stepwise logistic regression analysis revealed that the only independent risk factor for developing candidemia was the use of central venous catheters (P = 0.0001). Candida albicans was the most frequently isolated pathogen, accounting for 18 (48%) episodes of candidemia, followed by Candida tropicalis (19%) and Candida glabrata (11%). The crude mortality rate was 62%. On univariate analysis concomitant opportunistic infections, presence of non-Candida albicans species of Candida and neutropenia were shown to be predictive of death. Multivariate analysis revealed that the presence of non-Candida albicans strains of Candida was the only significant factor associated with a worse prognosis (P = 0.001). In conclusion, candidemia appears to be more common in patients with advanced HIV disease. Of the factors which influenced the onset of candidemia, use of central venous catheters seemed to be the most important one.

The goal of our study was to evaluate the incidence of heart involvement in AIDS patients during various stages of the disease. Between January 1988 to September 1991, we conducted a prospective study in 114 anti-HIV positive patients. The patients, whose mean age (+/- SD) was 34.6 +/- 5.4 years (range 20 to 54), were divided into three groups: anti-HIV positive asymptomatic (n = 31; 27%), AIDS related complex (ARC) group IV-A (n = 11; 10%), and AIDS subgroups IV-C1 (n = 62; 54%) and IV-D (n = 10; 9%). Overall, 84 patients (74%) were i.v. drug abusers, 24 (21%) were homosexuals, and six (5%) were partners at risk. Zidovudine (AZT) was administered to 94 patients (82%). Opportunistic infections and/or secondary malignancies were detected in 72 patients (63%). Electrocardiographic changes were of little clinical relevance. Of 72 AIDS patients, 47 (65.2%) presented a cardiac involvement: 12 subjects (16.6%) were affected by a dilated cardiomyopathy, 13 (18%) by pericardial effusion, three (4.1%) by mitral valve prolapse, four (5.5%) by myocarditis, five (6.9%) by valvular bacterial endocarditis, and 10 (13.8%) by alterations of left ventricle regional contractility. During a mean follow-up period of 44 months, 29 AIDS patients (40.2%) died. Death was attributed to a cardiac event in four patients; autopsy could be performed in 24 of the 29 patients who died. Our results demonstrate that heart involvement is present in 45.6% of HIV-infected patients, but only in the end-stage of the disease (AIDS) and it is presumably due to opportunistic infections and/or secondary malignancies.(ABSTRACT TRUNCATED AT 250 WORDS)
