Abstract
A 34-year-old male presented with lung shadow and was asymptomatic during medical examination. The patient had a prior history of thyroid tumors. Imaging manifestation showed a nodule in the medial segment of the right middle lobe, with partial obstruction of the distal bronchus within the lesion. Ground-glass and inflammatory nodules were observed in the anterior segment of the right upper lobe, as well as chronic inflammatory changes in the lower lobe of the right lung. Lung histopathological examination suggested invasive adenocarcinoma. A morphological examination of the bronchoalveolar lavage fluid revealed the presence of Tropheryma whipplei (TW) and Nocardia. Although TW infection has been reported in cancer patients, co-infection with Nocardia is a unique occurrence in this case. Opportunistic pathogens are common in immunocompromised patients but in this case, the patient was a young adult with normal immunity and an early-stage tumor with TW and Nocardia co-infection. We demonstrated the presence of rare microorganisms through imaging findings, combined with different staining methods of bronchoalveolar lavage fluid and lung tissue sections and evaluation of morphological characteristics. The aim of the present study was to provide early diagnosis and treatment of patients by improving microbial morphological detection.

Curr Probl Diagn Radiol 2023; 52:110-116. [PMID: 36333220 DOI: 10.1067/j.cpradiol.2022.09.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2022] [Revised: 09/12/2022] [Accepted: 09/21/2022] [Indexed: 02/05/2023]
Abstract
PURPOSE The aim of this study was to analyze chest CT imaging findings and relevant clinical factors in patients with HIV presenting to the emergency department (ED). MATERIALS AND METHODS A retrospective review was performed to identify patients with HIV who received chest CT imaging evaluation in the acute ED setting. Analyzed patients included adults with a known diagnosis of HIV who presented to the ED at a single tertiary care center between 2004 and 2020 and received chest CT imaging. Chest CT findings were assessed by 2 radiologist readers, and relevant clinical data were gathered. Statistical analysis was performed to determine if imaging and clinical factors demonstrate significant associations with CD4 count, viral load, and antiretroviral therapy status. RESULTS A total of 113 patients with HIV were identified who presented to the ED and underwent chest CT imaging evaluation (mean age 47 ± 11 years). Frequently detected chest CT findings included infectious pneumonia (24%), malignancy (11%), pleural effusion (17%), pericardial effusion (13%), and pulmonary embolism (4%). CD4 count, viral load, and active retroviral therapy demonstrated statistically significant associations with a number of key imaging and clinical factors, including presence of pneumonia, malignancy, average length of hospital admission, and survival. CONCLUSION Patients with HIV present with a wide range of imaging findings when presenting in the acute ED setting. CD4 count, viral load, and active retroviral therapy status demonstrate statistically significant associations with multiple key imaging findings and clinical factors. Chest CT plays an integral role in the clinical management of this unique patient population.

Abstract
BACKGROUND Human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) infection can lead to a broad spectrum of lung diseases, including infectious diseases and tumors. Recently, with the wide application of bronchoscopes and cytopathology of bronchoalveolar lavage fluid (BALF), the diagnostic efficiency of lung diseases has improved. The present study focuses on analyzing the cytopathologic characteristics of BALF in the diagnosis of HIV/AIDS-related lung disease and comparing the lung disease spectrum between HIV and HIV-uninfected patients. METHODS BALF specimens were collected from 2211 patients. Using ThinPrep liquid-based technology, the cytologic smears were prepared by staining with Hematoxylin and Eosin (HE), Gomori's methenamine silver (GMS), and Periodic Acid Schiff (PAS), acid-fast and immunocytochemical (ICC) staining. Real-time PCR was used to detect cytomegalovirus (CMV) and Mycobacterium tuberculosis (M. tuberculosis) in the remaining BALF. PCR-reverse dot hybridization was used for mycobacterial species identification. RESULTS From the 2211 BALF specimens, 1768 (79.96%) were specimens from HIV-infected patients, and 443 (20.04%) were speciments from HIV-uninfected patients. The HIV-infected patients with a median age of 38.5 ± 11.3 years were markedly younger than the HIV-uninfected patients (52.9 ± 14.9 years) (p < 0.01). We found that 1635 (92.5%) HIV-infected patients were males, showing a prominently higher proportion than those without HIV infection (71.1%) (p < 0.01). Meanwhile, 1045 specific lesions were found in 1768 HIV-infected patients (59.1%), including 1034 cases of infectious diseases and 11 neoplastic lesions, also exhibiting a distinctly higher proportion compared to the HIV-uninfected patients (12.2%) (p < 0.001). For the HIV-infected group, a distinctly higher proportion of single infection lesions (724/1768, 41%) was noted than the HIV-uninfected group (14/443, 3.2%) (p < 0.001). Among single infection lesions, the most common was Cytomegalovirus(CMV) infection (20.9%) for the HIV-infected group, followed by Pneumocystis jiroveci(PJ) (13.0%), Fungal (3.5%), and Mycobacterial infections (3.4%), of which M. tuberculosis infection accounted for 3.1%. Double infections (300/1768, 17.0%) and Triple infections (10/1768, 0.6%) were found only among the patients with HIV. The malignancies among HIV-infected patients included adenocarcinomas (0.22%), small cell carcinomas (0.2%), squamous cell carcinomas (0.1%), and diffuse large B-cell lymphoma (0.1%). HIV-infected patients exhibited a significantly lower incidence of neoplastic lesions (0.6% vs. 9.0%) than the HIV-uninfected patients (p < 0.001). CONCLUSIONS There was a significant difference in the spectrum of lung diseases between HIV-infected and non-infected patients diagnosed by BALF cytopathology.

Abstract
With the advent of anti-retroviral therapy, non-AIDS-related comorbidities have increased in people living with HIV. Among these comorbidities, pulmonary hypertension (PH) is one of the most common causes of morbidity and mortality. Although chronic HIV-1 infection is independently associated with the development of pulmonary arterial hypertension, PH in people living with HIV may also be the outcome of various co-morbidities commonly observed in these individuals including chronic obstructive pulmonary disease, left heart disease and co-infections. In addition, the association of these co-morbidities and other risk factors, such as illicit drug use, can exacerbate the development of pulmonary vascular disease. This review will focus on these complex interactions contributing to PH development and exacerbation in HIV patients. We also examine the interactions of HIV proteins, including Nef, Tat, and gp120 in the pulmonary vasculature and how these proteins alter the endothelial and smooth muscle function by transforming them into susceptible PH phenotype. The review also discusses the available infectious and non-infectious animal models to study HIV-associated PAH, highlighting the advantages and disadvantages of each model, along with their ability to mimic the clinical manifestations of HIV-PAH.

Abstract
BACKGROUND A newly diagnosed HIV patient with tuberculosis-like symptoms was confirmed with disseminated nocardiosis involving the central nervous system (CNS). This case report provides novel insights into the diagnosis and treatment of nocardiosis. CASE PRESENTATION A 44-year-old male newly diagnosed HIV patient presented on March 20, 2017, with the major symptoms of fever and headache. Computed tomography (CT) of the chest showed a mass in the lower lobe of the right lung. Brain magnetic resonance imaging (MRI) revealed multiple abnormal signals and ring enhancement. Blood culture suggested the presence of mycobacteria and positive acid-fast staining, and the strain was identified as Nocardia. He was administered an anti-infective therapeutic regimen consisting of cefotaxime sodium and sulbactam sodium (2.25 g, qid, iv), linezolid (0.6 g, bid, iv), moxifloxacin (0.4 g, qd, iv), sulfamethoxazole (1.44 g, qid, per os), and amikacin (0.4 g, qd, iv). After treatment, fever and skin nodules resolved, and reexamination by chest CT and brain MRI suggested improvement compared with the pretreatment situation. CONCLUSIONS At present, there are few reports of disseminated Nocardia infection involving the CNS in HIV patients in China. This case report will help to enhance the understanding of disseminated Nocardia infection. In the process of clinical diagnosis and treatment, Nocardia may be initially misdiagnosed as disseminated TB. In the present case, tuberculosis-like symptoms actually corresponded to disseminated nocardiosis involving the CNS.

Abstract
This case report discusses the rare presentation of cytomegalovirus (CMV) pneumonitis in a young patient with moderately severe Crohn's disease managed with low dose azathioprine. CMV pneumonitis was initially suspected on CT chest images and confirmed by PCR for CMV. She was treated with intravenous ganciclovir and later stepped down to oral valganciclovir. Although this patient had a prolonged and complicated hospital admission, a good clinical outcome was achieved. CMV infection was raised as an early differential and antiviral treatment was started without delay. This case study, therefore, makes the case for increased awareness of the possibility of, and recognition of CMV pneumonitis among healthcare professionals as a way of preventing significant morbidity and mortality. It also raises awareness of checking for slow metabolisers of azathioprine before initiation to look for individuals who may be at increased risk of azathioprine's adverse effects.

Abstract
In both the post and pre combination antiretroviral therapy (cART) era, Pneumocystis jirovecii and Toxoplasma gondii remain common opportunistic infectious agents. The common manifestations are pneumonia for P. jirovecii and brain abscess for T. gondii. Nevertheless, co-infection remains rare, and pulmonary toxoplasmosis is scarce, or may be underestimated because of its similarity with Pneumocystis jirovecii pneumonia. We reported an uncommon case of an AIDS patient (6 CD4 + T cells/mm³) with both pulmonary and cerebral toxoplasmosis associated with pneumocystis pneumonia. The patient presented with general weakness, fever and dyspnea. Pulmonary toxoplasmosis and pneumocystis were confirmed by microscopic examination and DNA detection in the bronchoalveolar lavage. Computed tomography imaging of the brain revealed a single characteristic cerebral toxoplasmosis lesion of the left capsular area. He was successful treated by trimethoprim/sulfamethoxaxole in conjunction with an early reintroduction of cART, and without IRIS development. During a 3-year follow-up, HIV viral load remained undetectable, and the patient did not relapse for toxoplasmosis or Pneumocystis pneumonia.

Abstract
BACKGROUND Cytomegalovirus (CMV) pulmonary involvement is rarely associated with IRIS; therefore, limited information is available. CASE PRESENTATION Here, we describe the case of a 43-year-old HIV-infected male who developed an unusual case of IRIS after cytomegalovirus (CMV) pneumonia. Clinically there was a progressive and paradoxical worsening of respiratory distress, despite being treated for CMV after initiation with antiretroviral therapy. Chest X-ray revealed disseminated infiltrates in both lungs; chest CT-scan showed generalized lung involvement and mediastinal adenopathy. Pulmonary biopsy confirmed CMV pneumonia with the observation of typical viral inclusions on pneumocytes. CONCLUSIONS CMV pneumonia can be associated with the development of IRIS requiring treatment with immunosuppressant's and immunomodulatory drugs.

Abstract
Background Tuberculosis (TB) screening among patients infected with Human Immunodeficiency Virus (HIV) is one of the approaches for controlling TB-HIV co-infection. The absence of typical TB symptoms among HIV-infected patients makes diagnosis challenging. Identifying predisposing risk factors of TB among HIV-infected patients could possibly guide TB diagnosis and treatment. This study was designed to identify some important factors associated with TB among HIV-infected patients and to quantify the strength of this association. Methodology In 2010, a case control study was conducted in Khartoum State, Sudan. Cases and controls were selected by simple random sampling with a 1:2 ratio; 97 cases and 194 controls were enrolled in the study. A logistic regression model was built to estimate and quantify the strength of the association between the study variables and the outcome; a p-value less than 0.05 was considered the cut-off point for a significant statistical association. Results Past history of TB, CD4 count < 200 cells/µl, late clinical stages, non-employment, and no formal education were found to be risk factors for developing TB among HIV-infected patients. The adjusted ORs and 95% CIs were (6.9: 3.75–12.99), (4.8: 1.57–15.26), (5.8: 1.88-17.96), (2.5: 1.26–5.03), and (2.5: 1.28–4.63), respectively. Poor adherence, marital status, age, and gender are not associated with developing TB among HIV patients. Conclusion HIV patients who have at least one of the risk factors found in this analysis are at higher risk of TB; therefore, they should be screened more frequently and treated promptly, especially HIV patients with previous TB.

Abstract
Toxoplasmosis complicating lung cancer has been described only rarely. Here, we report a case of acute Toxoplasma gondii infection in a patient with squamous lung cancer. A 64-year-old woman was admitted to our hospital with a history of cough of 6 months' duration and chest pain of 1 week's duration. Further examination revealed multiple swollen lymph nodes, palpable on the top of the right collarbone and without tenderness. The chest X-ray, bronchoscopy, and computed tomography scan confirmed squamous carcinoma of the right lung. The Wright-stained bronchoalveolar-lavage fluid cytology diagnosis was positive for T. gondii and tachyzoites were detected. All of them were of free type (ectocytic), without intracellular parasites. Serological examination revealed that the anti-T. gondii immunoglobulin (Ig) M and IgG antibodies were positive. Unfortunately the patient did not continue treatment and was lost to follow-up. Toxoplasmosis is a life-threatening opportunistic infection in patients with lung cancer. Prompt recognition of T. gondii infection among cancer patients with subsequent targeted treatment of toxoplasmosis could help alleviate symptoms and improve survival.

Abstract
Pulmonary infection is one of the most frequent causes of morbidity and mortality throughout the world. Many infections occur in individuals with concomitant intrapulmonary or extrathoracic diseases; however, they commonly develop in otherwise healthy people. In the non-immunocompromised population, pneumonia is the most prevalent community-acquired infection and the second most common nosocomial infectious disorder. In immunocompromised patients, in children, and in the elderly, pneumonia, as well as other pulmonary infections, may develop into a life-threatening condition.

Abstract
Cytomegalovirus (CMV) is an important cause of morbidity and mortality in immunocompromised patients. Although immunosuppressive therapy is the mainstay of medical treatment for patients with inflammatory bowel disease, the importance of CMV as a cause of pneumonia in this group is less well recognised. This case report presents a case of shortness of breath, dyspnoea and fever in a 51-year-old man with Crohn's disease on azathioprine and highlights the importance of considering CMV as a cause of pneumonia in this group.

Abstract
The spectrum of pulmonary diseases that can affect human immunodeficiency virus (HIV)-infected patients is wide and includes both HIV and non-HIV-related conditions. Opportunistic infections and neoplasms remain a major concern even in the current era of combination antiretroviral therapy. Although these diseases have characteristic clinical and radiological features, there can be considerable variation in these depending on the patient's CD4 lymphocyte count. The patient's history, physical examination, CD4 count and chest radiograph features must be considered in establishing an appropriate diagnostic algorithm. In this article, we propose different diagnostic approaches HIV infected to patients with respiratory symptoms depending on their clinico-radiological pattern.

Abstract
INTRODUCTION Complete delineation of the HIV-1 life cycle has resulted in the development of several antiretroviral drugs. Twenty-five therapeutic agents belonging to five different classes are currently available for the treatment of HIV-1 infections. Advent of triple combination antiretroviral therapy has significantly lowered the mortality rate in HIV patients. However, fungal infections still represent major opportunistic diseases in immunocompromised patients worldwide. AREAS COVERED Antiretroviral drugs that target enzymes and/or proteins indispensable for viral replication are discussed in this article. Fungal infections, causative organisms, epidemiology and preferred treatment modalities are also outlined. Finally, observed/predicted drug-drug interactions between antiretrovirals and antifungals are summarized along with clinical recommendations. EXPERT OPINION Concomitant use of amphotericin B and tenofovir must be closely monitored for renal functioning. Due to relatively weak interactive potential with the CYP450 system, fluconazole is the preferred antifungal drug. High itraconazole doses (> 200 mg/day) are not advised in patients receiving booster protease inhibitor (PI) regimen. Posaconazole is contraindicated in combination with either efavirenz or fosamprenavir. Moreover, voriconazole is contraindicated with high-dose ritonavir-boosted PI. Echinocandins may aid in overcoming the limitations of existing antifungal therapy. An increasing number of documented or predicted drug-drug interactions and therapeutic drug monitoring may aid in the management of HIV-associated opportunistic fungal infections.
