Does COVID-19 Vaccination with BNT162b2 Influence HIV-Related Immunological and Virological Markers? Data from 235 Persons Living with HIV at Cotugno Hospital, Naples, Italy: Immune Response After Second and Third Doses, and Influence on Immunovirological Markers.

Few data are available on the impact of COVID-19 vaccination on CD4 counts and HIV-RNA in persons living with HIV (PLWH). We present the data of 235 PLWH who were vaccinated with BNT162b2 in March 2021-February 2022 at the "Cotugno" hospital in Naples. PLWH treated at the "Cotugno" hospital, who were vaccinated at the hospital vaccination center, without prior COVID-19 and for whom immunological/virological data were available in the last 12 months and in the 6 months after vaccination were included. Antispike Ab were available for 187 and 64 PLWH after the second and third doses: PLWH with antispikes >33 binding antibodies units (BAU)/mL increased from 91% to 98%. Antinucleocapsid Ab performed in 147 and 56 patients identified 19 (13%) asymptomatic/paucisymptomatic COVID-19 infections after the second dose and an additional 15 (27%) after the third dose. Immunological/virological data were collected before vaccination (T0), after the second dose (T1), and after the third dose (T2). The absolute number of CD4 increased after the third dose (median 663, 657, and 707 at T0, T1, and T2; p < 0.000 T0 vs. T2). The proportion of patients with HIV-RNA <50 copies/mL increases significantly after the second dose (73%; 85.7%; 87.7%; p < 0.000 T0 vs. T2). The presence of COVID-19 asymptomatic/paucisymptomatic infections (demonstrated by the presence of antinucleocapsid Ab) significantly increases SARS-CoV-2 antispike Ab after second dose, but not after third dose. Asymptomatic/paucisymptomatic COVID-19 infections do not have influence on CD4 cell number and HIV-RNA level. Similarly, the presence of not-controlled HIV-RNA (HIV-RNA >50 copies/mL) does not influence antispike Ab response. According to our data, the response to SARS-CoV2 vaccination is effective in people living with HIV. Vaccination against COVID-19 appears to positively affect immunological and virological levels in people living with HIV.

New developments in magnetic resonance imaging of the nail unit.

The evolution of dedicated magnetic resonance imaging (MRI) musculoskeletal equipment allows new sequences and better images of the nail unit. The use of MRI has modified the imaging strategies used in treating inflammatory arthritis. In the case of psoriatic arthritis (PsA), the MRI study of the nail unit identifies nail involvement, which appears as an initial lesion for the induction of distal phalanx damage and consequently of distal interphalangeal joint arthritis. All patients with psoriasis, even in the absence of a clinically evident onychopathy, show characteristic MRI changes in the nail. This evidence could have a practical diagnostic value, because MRI study of the nail could document diagnosis in patients with undifferentiated spondyloarthropathies who have a barely evident psoriasis. We discuss the advantages and problems related to the use of low-field and high-field MRI in the study of the nail unit of patients with PsA.

Screening and monitoring of latent tubercular infection in patients taking tumor necrosis factor-α blockers for psoriatic arthritis.

Patients with arthritis who need treatment with biologics are carefully screened for possible previous exposure to tuberculosis to detect any latent tubercular infection (LTBI). The traditional method of screening for LTBI is not specific, because positivity could also depend on infection by atypical mycobacteria and bacillus Calmette-Guerin vaccination. In addition, the screening does not show high sensitivity, frequently presenting a false negativity because of immunosuppression caused by drugs used for arthritis. Recently, interferon-γ release assays (IGRA) have been used to screen LTBI with more sensitivity and specificity before treatment with anti-tumor necrosis factor-α drugs. Moreover, in our experience, IGRA are potentially useful in monitoring LTBI during biologic therapy.

Adherence to antiretroviral therapy thought package-refill among HIV+ persons at "D. Cotugno" hospital, Naples, Italy.

Background: A gold-standard for the measurement of adherence to antiretroviral therapy (ART) is lacking. Aim of this study is to verify the feasibility of a package-refill-based measurement of ART at "D. Cotugno" hospital, Naples, Italy, and the factors associated to adherence. Methods: In the period January 2018-August 2020, we calculated the package-refill as the ratio between ART-packages actually withdrawn, and the ART packages needed to regularly take ART. Adherence was associated, trough a univariate e multivariate logistic regression, to demographical, behavioural and clinical factors. Results: 1140 HIV+ subjects were included. At univariate logistic regression inadequate package-refill-based adherence is associated with HIV-RNA higher than 50 copies/mmL (OR 3.77-IC95% 2.76-5.13) and with HIVRNA higher than 200 copies/mmL (OR 3.98-IC95% 2.69-5.90). Being not-Italian and Injective-drug-user are associated with low adherence, having HIV/AIDS for more than 8 years is associated with better adherence. Conclusions: Package-refill is a suitable method for measuring adherence and is associated with the condition of viral failure.

Extra-articular manifestations in psoriatic arthritis patients.

Psoriatic arthritis (PsA) is an inflammatory rheumatic disorder, associated with skin and/or nail psoriasis. It has been included in the spondyloarthropathies (SpA) group, with which it shares clinical, radiologic, and serologic features and familial and genetic relationship. Inclusion of disease among SpA is also based on their striking points of similarity for extra-articular manifestations (EAMs). The aim of study was to describe the EAMs in patients with PsA, evaluating the prevalence and clinical features associated with established and early PsA. The study was a retrospective analysis of case records of 387 PsA patients. Data recorded were demographic data, disease properties, laboratory tests, drug use, and presence of EAMs. Of 387 PsA patients, 190 have shown EAMs: 33.16 % had bowel involvement, 32.63 % ocular, 28.42 % cardiovascular, 25.79 % urogenital, 8.42 % skin (excluding psoriasis), 1.05 % pulmonary, and 0.53 % renal. A higher prevalence of EAMs was found in axial subset (p < 0.0001) and in established PsA patients (p = 0.03). The disease activity in PsA patients with EAMs was significantly higher (p < 0.0005). Smoker PsA patients had a significantly higher prevalence of EAMs than nonsmoker PsA patients (p < 0.0005). EAMs in PsA patients are common than expected and frequently associated with established form and axial subset. EAMs were more frequent in male gender, and the contemporary presence of male gender and axial subset showed a higher risk to develop EAMs. EAMS were more frequent in patients with a long disease duration and active disease. Moreover, these results suggest that in PsA patients, an initial checkup and a regular screening for EAMs are requested to ensure an appropriate management.

Biological therapies for spondyloarthritis.

Biological therapies and new imaging techniques have changed the therapeutic and diagnostic approach to spondyloarthritis. In patients with axial spondyloarthritis, tumor necrosis factor α (TNFα) inhibitor treatment is currently the only effective therapy in patients for whom conventional therapy with nonsteroidal anti-inflammatory drugs (NSAIDs) has failed. TNFα inhibitor treatment is more effective in preventing articular damage in peripheral joints than in axial ones. It is important to treat patients at an early stage of disease to reduce disease progression; moreover it is necessary to identify causes of therapy inefficacy in preventing joint damage in the axial subset.

Discovertebral erosions in patients with enteropathic spondyloarthritis.

OBJECTIVE: Magnetic resonance imaging (MRI) is considered the modality of choice for the diagnosis of spondyloarthropathy (SpA)-related spondylodiscitis, or discovertebral erosions (DE). Our aim was to analyze the prevalence and the clinical features of DE in patients with enteropathic SpA (EA) using MRI. METHODS: We evaluated 72 patients with EA and 43 controls for the study. All patients and controls underwent rheumatological and gastroenterological clinical examinations, and demographic features were recorded. For each patient, these factors were also recorded: duration of inflammatory bowel disease and arthritis from onset to enrollment, history of viral and bacterial infections, and occurrence of previous major trauma to the spine. These scores were taken: Bath Ankylosing Spondylitis Metrology Index (BASMI), Bath Ankylosing Spondylitis Functional Index (BASFI), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Harvey-Bradshaw Index, and the Simple Clinical Colitis Activity Index. All subjects had MRI of the spine. RESULTS: On the basis of inclusion criteria, 43 patients with EA were included in the study. Twenty-three had axial EA (axEA) and 20 had axial and peripheral subset EA (overlap subset or peripheral type 3; axphEA). Twenty-two patients with EA (15/7 axEA/axphEA) showed DE (30.55%; p < 0.001). DE was significantly more prevalent in axEA subjects than in the overlap subset (p < 0.001). In axEA, DE had a significant direct correlation with arthritis duration (r = 0.546, p = 0.007). Patients with DE showed BASDAI, BASMI, and BASFI scores significantly higher than patients without DE (p < 0.001). CONCLUSION: We found a high prevalence of DE among patients with EA (30.55%), confirming that DE is an important characteristic aspect of SpA. We found a high prevalence in patients in the axphEA subset (31.82%), suggesting that DE could be a characterizing feature of the overlap subset.

Prevalence of thyroid autoimmunity in patients with spondyloarthropathies.

OBJECTIVE: To evaluate the prevalence of chronic autoimmune thyroiditis or Hashimoto's thyroiditis (HT) in a group of patients with spondyloarthritis (SpA). METHODS: We evaluated serum levels of thyroid-stimulating hormone, free triiodothyronine, and free thyroxine, and titers of antithyroglobulin and antithyroid peroxidase (anti-TPO) antibodies in 357 consecutive patients with SpA. We also recruited 318 healthy age-matched controls. Ultrasonography of the thyroid gland was performed in all subjects and rheumatic activity was evaluated. RESULTS: Indices of thyroid autoimmunity were significantly more frequent in patients with SpA than in controls (24.09% vs 10.69%, respectively; p < 0.05). In the SpA group, a higher prevalence of HT was found in patients with an active disease than in those with low-moderate disease levels. Also in the SpA group, patients with a disease duration > 2 years had a higher prevalence of HT and anti-TPO antibodies positivity than patients with a disease duration ≤ 2 years. Ultrasonography detected a significantly higher frequency of thyroid nodules and hypoechoic pattern in patients with SpA than in controls. Among patients with SpA, HT and anti-TPO antibodies positivity were significantly more frequent in patients with peripheral involvement (68.6%) than in patients with axial involvement (31.4%; p < 0.05). CONCLUSION: Our study shows a significantly higher prevalence of thyroid autoimmunity in patients with SpA as compared to controls. Thyroiditis occurs more frequently in patients with longer disease duration and active rheumatic disease. We suggest that thyroid function tests be part of the clinical evaluation in patients with SpA.
