Profile of Newly Diagnosed Patients with HIV Infection in North-Eastern Romania

Background and Objectives: Human immunodeficiency virus infection and the acquired immunodeficiency syndrome (HIV/AIDS) pandemic are unquestionably the most serious public crisis of our time. Identifying, preventing, and treating HIV-associated comorbidities remains a challenge that must be addressed even in the era of antiretroviral therapy. Materials and Methods: In this study, we aimed to characterize the aspects of newly diagnosed patients with HIV/AIDS, during 2021-2022 in Northeastern Romania. We reviewed the frequency and associated comorbidities of these patients in correspondence with national and global results. Results: Our study found that of all newly diagnosed HIV cases (167 cases-74 cases in 2021 and 98 cases in 2022), 49.70% were diagnosed with HIV infection and 50.30% had AIDS. Based on sex correlated with the CD4+ T-lymphocyte level, the most affected were males, with a lower CD4+ T-lymphocyte level overall. The average HIV viral load was 944,689.55 copies/mL. Half of males had an abnormal ALT or AST (39.53% and 49.61%); as for the females, less than a quarter had an increased value of ALT or AST, respectively (18% and 26%). The most frequent co-infections were as follows: oral candidiasis (34.73% of patients), hepatitis B (17.37% of patients), and SARS-CoV-2 infection (8.38%), followed by hepatitis C (6.39%), tuberculosis (TB), syphilis, toxoplasmosis, Cryptococcus, Cytomegalovirus infections. Males were more affected than females, with a higher percentage of co-infections. The prescribed antiretroviral treatment focused on a single-pill regimen (79.04%) to ensure adherence, effectiveness, and safety. Therefore, 20.96% had been prescribed a regimen according to their comorbidities. Conclusions: Our study found a concerning rise in the incidence of HIV in 2022 compared to that in 2021 in Northeastern Romania, because of the rise in post-SARS-CoV-2 pandemic addressability. Advanced immunodeficiency and the burden of opportunistic infections characterize newly diagnosed HIV patients. The physicians should keep in mind that these patients may have more than one clinical condition at presentation.

Diagnostic and prognostic value of presepsin in the emergency department

Sepsis syndrome is a common situation and has devastating implications on health care systems worldwide. Biomarkers may have an important role to highlight the presence, absence or severity of sepsis.

MATERIAL AND METHODS

Retrospective study is conducted on a group of 95 suspected sepsis patient (0.16%) out of a total of 56,996 patients that were presented in the Emergency Department/Emergency County Hospital "St. Spiridon" from Iaşi during 01.01.2012-01.12.2012. The study aims to establish the following: the incidence of sepsis diagnosis, analysis of prognostic factors, relationship between the presepsin value and clinical outcome.

RESULTS

In men, there was a distribution of cases between the age of 22 years up to 89 years with an average confidence interval between 59.32 and 67.23 years, and the distribution of cases varies among women from age of 40 years up to 93 years, with an average confidence interval between 65.53 and 75.47 years The most frequent primary source of infection is localized at the pulmonary level, in a total of 21.1%, followed by abdominal location occurring in a total 14.7%. Area under the curve in ROC curve analysis regarding mortality showed significant values of area for presepsin (0.859), leukocytes (0.790), traumatic injuries association (0.761) and the presence of gastrointestinal history.

CONCLUSIONS

Presepsin has diagnostic value, early prognostic value and is an early marker of mortality in septic patients. Trauma associated with severe systemic infection leads to an increase in mortality.

The HIV-positive patient in intensive care--psychological profile

AIM

This paper aims to outline the profile of HIV-positive patients in intensive care, in terms of psycho-emotional and vital parameters.

MATERIAL AND METHODS

We evaluated the HIV-positive patients that required intensive care (IC), from January 2011 to December 2013, in the HIV/AIDS Regional of the "Sf. Parascheva" Infectious Diseases Clinical Hospital Iaşi.

RESULTS

From January 2011 to December 2013, the HIV/AIDS Regional Centre in Iaşi recorded 2649 hospitalizations, of which 0.67% (18 cases) required intensive medical care. Of these 10 were males and 8 females, aged between 24 and 65 years with a median of 24 years. There were 29 deaths (1.09% of all hospitalizations), 11 of which in intensive therapy (38% of all deaths)--7 men and 4 women. CD4 counts in persons requiring IC care were between 1 and 112/mm3, and most naive patients who died were late-presenters. The main diseases diagnosed were pulmonary tuberculosis and pneumocystosis, the main cause of death being multiple organ failure. The duration of hospitalization ranged between 4.5 and 30 days. Treatment success rate was correlated with the CD4 and biological status: liver and renal failure, respiratory failure, meningeal coma, hypoproteinemia, diselectrolitemia. From a psychological perspective, patients that arrived in the intensive care showed a history of non-compliance and non-adherence, a personality structure often marked by a lack of respect for them, indifference or ignorance regarding the factors that generate well-being.

CONCLUSIONS

HIV-positive patients in the position of requiring intensive care showed a marked immunological collapse due to abandonment of therapy or late detection.

The psycho-emotional profile of the HIV-positive naïve patient

AIM

The paper aims to outline the naïve HIV-positive patient's profile, in terms of feelings and emotions post-diagnosis.

MATERIAL AND METHODS

The evaluation took place from January 2011 to December 2013 in the Psycho-social Assistance Office of the "Sfânta Parascheva" Infectious Diseases Hospital in Iaşi. We evaluated 146 patients newly diagnosed with HIV infection, both in terms of immunological and virusological and from a psychological perspective, using the Hamilton Anxiety Scale (HAMA), Beck Depression Inventory II (BDI) and the clinical interview.

RESULTS

In a period of 3 years (January 2011 - December 2013) we registered in the HIV/AIDS Regional Center in Iaşi, 146 new cases of HIV infection in adults, with distribution by years as follows: 46 in 2011, 45 in 2012, 55 in 2013; 39 cases were in Iaşi, 39 in Suceava, 26 in Botoşani, 18 in Neamţ 18, 16 in Bacău and 6 in Vaslui. Of these, 51 were women and 95 men, aged between 24 and 46 years. From the immunological point of view, 11% of patients had values of CD4 > 500 (16 patients), 47% between 500 and 100 (69 patients) and 42% < 100 (61 patients). From a psychological perspective, the clinical interview revealed a state of fear in 68.5% of cases (fear of death, fear of complications, fear of other people's reaction to the diagnosis), confusion in 62% of cases (in terms of diagnosis, the mode of infection, the future), anger in 27% of cases (against the source of infection, against themselves, against God or divinity), guilt and self-blame in 7% of cases. Beck Depression Inventory (BDI) revealed moderate depression in 14% of patients; mild depression in 27% of patients and 58% of patients presented no symptoms of depression. Regarding the anxiety scale HAMA, in 54% of cases it showed mild anxiety, average anxiety in 28% of cases, 14% severe anxiety and 3% (4 cases) very severe anxiety.

CONCLUSIONS

Patients newly diagnosed with HIV are a vulnerable population with a specific psycho-emotional profile. Multidisciplinary knowledge--in medical, psycho -emotional and social terms--of the patient's characteristics and needs helps to support adherence to the antiretroviral therapy and improve the quality of life.

Clinical-epidemiological trends of herpes zoster: a 5-year study

Herpes zoster (shingles) is a neurocutaneous viral disease, in recent years its incidence increasing throughout the world.

AIM

To study the incidence of herpes zoster among Iasi county patients requiring hospital admission and to analyze the clinical and epidemiological features and socioeconomic status of the study group.

MATERIAL AND METHODS

Retrospective study of 158 patients admitted to the largest clinical dermatology department in North-eastern Romania, the Clinical Dermatology Department of the Iasi "Sf. Spiridon" University Emergency Hospital. The study was conducted over a period of five years and included the analysis of epidemiological data, socioeconomic status, clinical forms of disease, associated diseases, pathology reports for skin biopsy fragments, administered treatment, and disease course.

RESULTS

This study confirms that shingles is not a sex-specific disease, the female/male ratio being 1.22: 1. Most patients belonged to the age group 70-80 years, accounting for about 35% of all patients, followed by the age group 60-70 years (24.6% of cases). A slight increase in the number of cases was recorded in autumn and summer in patients living in rural areas. 1.3% of the cases were diagnosed both with the disseminated form of disease, and complications (eczematization, bacterial superinfection, skin necrosis). 7.6% of patients presented additional skin disorders (pityriasis versicolor, impetigo, psoriasis vulgaris, mucocutaneous candidiasis), which raised the suspicion of an immune deficiency predisposing to shingles. The absence or late initiation of specific antiviral therapy correlated with prolonged hospital stay up to 4-6 days. We found an association between the erythematous form of shingles and young age, while the hemorrhagic or necrotic forms were present in the elderly and/or ill patients. The course was favorable and the length of illness was significantly shortened when the treatment adequate to the clinical form was administered. Associated comorbidities (essential hypertension 38.6%, dyslipidemia 24.6%, diabetes, mellitus 9.49%, chronic venous disease, other skin diseases) represent a factor complicating the development of herpes zoster by the cumulative stress the body is exposed to.

CONCLUSIONS

The main statistically significant epidemiological data in the study group are: older age (over 60 years), associated diseases (which by the marked imbalances induced in the body increase the risk of varicella zoster virus reactivation) intense psychological stress. The following parameters did not change the risk of developing shingles: area of origin, sex, the season at disease onset, number of hospital days, and administered treatment. Early diagnosis and treatment of this disease is important for maintaining a good quality of life, to avoid complications, to limit the extent of the disease and its transmission to others.

Interdisciplinary correlations regarding the clinical and paraclinical evaluations in HIV-positive pregnant women

HIV infection in pregnancy has an increasing prevalence due to the effectiveness of antiretroviral therapy. The risk of HIV vertical transmission varies between 15-20 % in European women who do not breastfeed and 25-40% in African mothers who breastfeed. The most important predictive factor of the vertical transmission is maternal plasma HIV viral load. Vertical transmission can be largely prevented by prenatal screening, perigestational ART, an adapted obstetrical attitude and exclusively artificial feeding of the infant.

MATERIAL AND METHOD

The study included 36 HIV-positive pregnant women, between 2012-2014, at age of 25-32 years.

RESULTS AND DISCUSSIONS

It has been found that the birth weight was less than 2,700 grams in all newborns of HIV-positive pregnant women or those with advanced disease (AIDS) and, also, they received an APGAR score less than 7. The primordial desideratum is to decrease the rate of mother-fetus vertical transmission, thus the caesarian section has been established as the birth method in all HIV-positive pregnant women after 38 weeks of amenorrhea, on intact membranes, outside labor, resulting in halving the percentage of HIV-positive children. A very important role belongs to the interdisciplinary collaboration between the obstetrician and the infectious diseases specialist during the pregnancy, but also during the postpartum period. The role of the obstetrician is present in all the moments of pregnancy evolution. The HIV-positive pregnant woman is included in the group of high risk pregnancies.

Influence of antibiotic therapy prior to admission on the efficacy of classical methods for the diagnosis of meningococcal disease

AIM

To assess the influence of preadmission antibiotic therapy on the results of the classical methods for bacteriological confirmation of meningococcal disease (MD).

MATERIAL AND METHODS

Retrospective study of the MD cases diagnosed in the "St. Parascheva" Universitary Clinical Infectious Diseases Iaşi between 1994 and 2011.

RESULTS

The etiological diagnosis was made by identifying the meningococcus in the CSF (cerebrospinal fluid) in 71.9% of the 323 patients and by blood culture in 8%. Preadmission antibiotic therapy received 39% of the patients, thus the sensitivity of test was significantly reduced: direct examination from 64.6% to 43.2% (p < 0.001), cultures from 55.9% to 27.2% (p < 0.001), and latex-agglutination from 84.6% to 58.8% (p = 0.003). The rate of positive CSF decreased from 82.1% to 56% (p < 0.001). Preadmission antibiotic therapy significantly increased the ratio of cases in which meningococcus was not detected in CSF by any of the classical methods (44% compared to 17.9% in the cases without prior treatment). The proportion of cases in which meningococcal isolation was done by two methods decreased from 38.5% to 19.2%, and of those by all three methods from 16.9% to 5.6% (p < 0.001). Preadmission antibiotic therapy also decreased the rate of positive blood cultures from 14.7% to 3.5% (Fisher's exact test, p = 0.009).

CONCLUSIONS

Antibiotic treatment prior to admission significantly decreases the percentage of patients with MD in which meningococcal isolation can be done; this requires the use of a more sensitive diagnosis method (ex. qPCR).

Side effects of antiviral therapy in hepatitis C virus infection-sarcoidosis - case report

Standard therapy in chronic hepatitis C virus infection is still a combination of peginterferon alfa2a/2b and ribavirin for 48 weeks. As of side effects, there are organic side effects, such as hematologic disorders, and functional side effects, reflected in the quality of life of hepatitis C patients. Up to 30% of the patients develop specific side effects such as headache, fever, fatigue. Sarcoidosis, known as a granulomatous disease of uncertain cause, is an uncommon finding in this category of patients. This cause-effect relation is accounted for by the convergent action of peginterferon and ribavirin of stimulating type 1 T helper cells and reducing type 2 helper T cells activation. We present the case of male patient known with chronic hepatitis C who developed pulmonary sarcoidosis following antiviral therapy. The first manifestation of the disease was unexplained fever accompanied by pulmonary tract disease. The diagnosis was established by immunophenotyping in bronchial aspirate

Diagnosis of meningococcal infection by QPCR: detection and quantification of DNA / Neisseria meningitidis

We present the case of a patient with clinical signs of meningococcemia and negative bacterial culture. Microbiological diagnosis was possible only by testing with real time PCR technique the cerebrospinal fluid and blood samples. Both pathologic samples were positive for Neisseria meningitidis by this rapid and sensitive diagnostic method.

Diagnostic approaches in infective endocarditis

Infective endocarditis is a true systemic infection and a life-threatening disease associated with high mortality.

AIM

To evaluate the problems that occur during making the diagnosis of infective endocarditis, in order to highlight the need of other diagnostic prospects.

MATERIAL AND METHODS

Retrospective study using clinical, microbiological, and echocardiographic findings from 45 patients admitted to the Iasi Infectious Diseases Hospital in the interval January 2007 - January 2011.

RESULTS

A positive diagnosis of infective endocarditis was made based on Duke Criteria. Inflammatory syndrome revealed leukocytosis with neutrophilia in 42% of the patients. In 91% of the cases fever syndrome was present. Blood cultures were positive in almost 45% of the cases, and the identified etiologic agents were Staphylococcus spp., Streptococcus spp., Achromobacter spp., Klebsiella spp., Enterococcus spp., E. coli. In 95% of the patients, the echocardiographic appearance was a major criterion for diagnosis. Associated diseases were most often present with rebound on the course. Cardiac complications occurred despite treatment and re-evaluations. Ten percent of our cases required transfer to cardiology and cardiac surgery units.

CONCLUSIONS

Microbiologic diagnosis was mainly based on cultured-dependent methods that often fail because of previous antibiotic therapy or the involvement of fastidious microorganism. In this case, advances in molecular diagnostics have yielded new tools (polymerase chain reaction - PCR techniques) to diagnose this disease.

[The utility of QuantiFERON TB Gold for diagnosing tuberculous meningitis in children]

MATERIAL AND METHODS

We performed QuantiFERON-TB Gold in Tube (QFT-G) in blood and CSF at 40 children diagnosed with TB meningitis and at 39 children with non TB meningitis, admitted between October 2006 and December 2009.

RESULTS

The CSF analyses were suggestive for TB at 27 patients and only 14 had positive culture. The sensitivity of QFT-G in CSF was 72.72% and 69.44% in blood; specificity 96.96% in CSF and 89.18% in blood; the positive predictive value was 96% in CSF and 86.2% in blood; negative predictive value was 78.04% in CSF and 75% in blood. The sensitivity of TST was 61.76% and specificity 82.05%. The sensitivity of the culture from CSF was only 35%. The sensitivity and specificity of QFT-G was higher than TST and culture and better in CSF than in blood.

CONCLUSIONS

The determination of alpha-interferon in serum and CSF is useful diagnostic marker of tuberculosis who could improve the management of TB meningitis.

[MecA and pvl genes detection in Staphylococcus aureus strains isolated from lower respiratory tract infections]

Although community-acquired Staphylococcus aureus pneumonia with highly virulent Panton-Valentine leukocidin (PVL)-positive strains, a severe disease with significant lethality, is rare, especially in adult and adolescent patients, recent reports highlight that these infections are on the rise. On the other hand, methicillin-resistant S. aureus (MRSA) is one of the high-risk and potential multi-drug resistant microorganisms.

OBJECTIVES

The aim of this study was to investigate the prevalence of mecA and pvl genes in S. aureus strains isolated from lower respiratory tract infections and to assess the antibiotic resistance profile of these strains.

MATERIAL AND METHOD

The antibiotic susceptibility testing was performed by the disk diffusion method according to CLSI recommendations in 32 consecutive non-repeated S. aureus strains isolated from sputum specimens and endotracheal aspirates of hospitalized patients over the period from January 2005 to December 2009. Only 20 strains (2008-2009) were tested for the presence of mecA and pvl genes by real-time PCR and detection with specific fluorescence probes.

RESULTS

Of the 32 S. aureus isolates, 68.7% were MRSA. MRSA strains showed higher resistance rates to gentamicin, tetracycline, rifampicin, fluoroquinolones comparing to the methicillin susceptible ones. Only one strain produced pvl; it was isolated from a 7 year old child with lethal sepsis with pulmonary and meningeal secondary localisations.

CONCLUSIONS

Glicopeptides and linezolid are therapeutic options indicated in the treatment of staphylococcal pneumonia produced either by MRSA strains or pvl positive S. aureus strains.

[Risk factors for Pseudomonas aeruginosa infections, resistant to carbapenem]

Since their introduction in clinical practice,carbapenems have been among the most powerful antibiotics for treating serious infections cased by Gram-negative nosocomial pathogens, including Pseudomonas aeruginosa. The emergence of betalactamases with carbapenem-hydrolyzing activity is of major clinical concern. Pseudomonas aeruginosa is a leading cause of nosocomial infection.

RESULTS

Risk factors for colonization with carbapenems-resistant Pseudomonas in hospital are: history of P. aeruginosa infection or colonization within the previous year, (length of hospital stay, being bedridden or in the ICU, mechanical ventilation, malignant disease, and history of chronic obstructive pulmonary disease have all been identified as independent risk factors for MDR P. aeruginosa infection. Long-term-care facilities are also reservoirs of resistant bacteria. Risk factors for colonization of LTCF residents with resistant bacteria included age > 86 years, antibiotic treatment in the previous 3 months, indwelling devices, chronic obstructive pulmonary disease, physical disability, and the particular LTCF unit.

[Hanover intensive score. Study on 218 cases ]

We have performed a prospective study (1990-1996) in our intensive care unit in Hospital "C.I. Parhon" Iassy. Our study has 218 critical patients with ARDS and MSOD. For all of them we have used a new scoring system HIS (Hanover Intensive Score) for: the evaluation of patients with ARDS that have the risk to develop MSOD; determine the prognosis in different moments of evolution. In our opinion this score has the following advantages: it is easy to apply; it can determine the prognosis and the probable status of the patient at the moment of outcome; it can be used in our country with the technical that we have and we propose this score for his performances.
