Bone Marrow Aspiration/Biopsy in the Evaluation of Fever of Unknown Origin in Patients with AIDS.

BACKGROUND: HIV can interrupt the normal development of bone marrow cell lines. Bone marrow aspiration/biopsy (BMA/B) has been described as a diagnostic tool in AIDS patients with fever of unknown origin (FUO). In this review, we aimed to study patients with AIDS who had undergone a BMA/B to investigate FUO and describe the pathologies diagnosed in the biopsy. METHODS: Thirty-four BMA/B samples were collected from AIDS patients admitted for work-up of FUO to the infectious disease ward of a tertiary referral HIV center in Tehran, Iran, between September 2014 and September 2015. Data including age, sex, duration of disease, CD4 cell counts, hepatitis B (HBV) and C (HCV) coinfection, the primary presentation of AIDS, and the treatment history were retrieved and analyzed. Patients underwent BMA/B. An expert pathologist reviewed the BMA/B specimens. RESULTS: The mean age of the patients was 37.5 years (range, 26-56), and 27 (79%) were men. Twenty-seven (79%) patients contracted HIV from injection drug use, and 7 (21%) via sexual transmission. Only 3 (9%) of the BMA/B examinations were normal. Hypocellular bone marrow was diagnosed in 22 (65%) patients. Other pathologies included granulomas in 6 (18%), hematologic malignancies in 2 (6%), and leishmaniasis Aspergillosis, each in 1 (3%) patient. Six (17%) of the specimens were found to have tuberculosis infections. CONCLUSION: Hypocellular bone marrow was the most common pathology on BMA/B examinations, followed by the presence of granulomas. Tuberculosis, Aspergillosis, and Leishmaniasis the opportunistic infections diagnosed on BMA/B specimens. Our results support BMA/B as an appropriate diagnostic tool for early diagnosis of opportunistic infections and malignancies in AIDS. BMA/B is indispensable in the armament of diagnostic tools of the physicians managing AIDS patients.

Relationship Among HIV-Related Stigma, Mental Health and Quality of life for HIV-Positive Patients in Tehran.

People living with HIV/AIDS (PLHA) face several challenges in terms of the medical management of their disease. Alongside this are stigma, discrimination and psychosocial issues associated with HIV infection. In this study, the relationships associated with HIV-related stigma, mental health and quality of life for HIV-positive patients were investigated. This cross-sectional study examined a sample of 450 HIV positive patients from the Infectious Diseases and Behavioral Health Clinic of Imam Khomeini Hospital in the city of Tehran, Iran. PLWHA completed Socio-Demographic Characteristics, Berger Scale Stigma (BSS), General Health Questionnaire (GHQ-28), WHO Quality of life-BREF (WHOQOL-BREF) and Philips Social Support Appraisals (SSA). Stigma was significantly correlated with psychological variables, social support, and quality of life. A prevalence of psychiatric disorders was reported by 78.8%. Findings suggested that psychosocial interventions reduce HIV related stigma, address psychological disorders and build social support to improve quality of life for people living with HIV.

Early loss to follow-up and mortality of HIV-infected patients diagnosed after the era of antiretroviral treatment scale up: a call for re-invigorating the response in Iran.

In Iran, the HIV/AIDS epidemic is growing during an era of scaling up the national surveillance system and antiretroviral therapy programs. We examined the early loss to follow-up and mortality rates in a retrospective cohort of 1495 HIV-infected patients by survival proportional hazard Cox model. We also conducted a data abstraction sub-study in a systematic random sample of 147 patients to assess the association between mortality and predictor factors. Overall, 17.3% patients were not seen after their first visit and 17.4% more were lost by 6 months. The overall mortality rate was 7.0 (95% CI 6.1-8.1) per 100 person-years. Moreover, crude mortality rate was higher in men (8.6) than in women (1.7), with an age-adjusted hazard ratio for men compared to women of 4.55 (95% CI 2.31-8.93). Lastly, history of tuberculosis and not being on antiretroviral therapy were significantly associated with higher mortality in the patient sub-sample.

Evaluation of bone mineral density in Iranian HIV/AIDS patients.

Bone disorders have emerged as a worrisome complication in HIV-infected patients in recent years. It is not clear that HIV infection itself or antiretroviral treatment or both are causes of bone loss. However, most studies have found a high prevalence of osteopenia and osteoporosis in HIV/AIDS patients. The objectives of this study were to determine the prevalence of osteopenia and osteoporosis in HIV-infected patients either untreated or receiving Highly Active Antiretroviral Therapy as compared with HIV negative persons. We also assessed the factors associated with these conditions. Bone Mineral Density was assessed by Dual Energy X-Ray Absorptiometry scans at the hip and lumbar spine in 36 AIDS patients receiving antiretroviral therapy and 44 HIV infected patients not receiving antiretroviral therapy (naïve patients) and 40 HIV negative individuals as control. Factors that affect BMD were also determined. Prevalence of osteopenia or osteoporosis in different regions was significantly higher in HIV/AIDS patients compared with HIV negative subjects (77.3% in HIV positive naïve patients, 86.1% in HAART-treated patients and 60% in the control group, P=0.002). Mean serum alkaline phosphatase was higher in HIV/AIDS patients than the control group (P=0.003). Osteopenia and osteoporosis in HIV-infected patients were associated with duration of HIV infection (P<0.0001) and antiretroviral treatment (P=0.012). Prevalence of osteopenia and osteoporosis in HIV/AIDS patients was higher than HIV negative individuals. Osteopenia and osteoporosis in HIV/AIDS patients was associated with duration of HIV infection and antiretroviral treatment.

FNA diagnostic value in patients with neck masses in two teaching hospitals in Iran.

The FNA (fine needle aspiration) procedure is simple, inexpensive, available and a safe method for the diagnosis of a neck mass. FNA has numerous advantages over open surgical biopsies as an initial diagnostic tool; therefore we decided to compare the accuracy of this method with open biopsy. This retrospective as well as descriptive study comparing preoperative FNA results with existing data in the Pathology Department in Bu-Ali and Amir Alam Hospitals. Our study included 100 patients with neck masses of which 22 were thyroid masses, 31 were salivary gland masses, and 47 were other masses. Age ranged from 3 years to 80 years with the mean age of 42.6 years. There were 59 men and 41 women. The Sensitivity was 72%, Specificity 87%, PPV 85%, NPV 75% and diagnostic Accuracy 79%. In this study we had also 26% false negative and 15% false positive. FNA is a valuable diagnostic tool in the management of neck masses; also it has been used for staging and planning of treatment for the wide and metastatic malignancy. This technique reduces the need for more invasive and costly procedures. According to the high sensitivity and high accuracy in this study, FNA can be used as the first step of diagnoses test in neck masses.

Respiratory Complications in Iranian Hospitalized Patients with HIV/AIDS.

BACKGROUND: The respiratory tract has been the most commonly affected site of illness in HIV-infected patients. The current study was done to identify the frequency of respiratory complications in a consecutive case series of HIV-positive patients in Iran. MATERIALS AND METHODS: This study was a retrospective analysis at the national academic reference medical center of Imam-Khomeini Hospital, in Tehran, Iran. The study included 199 new admissions for 177 HIV-infected patients between 2000 and 2005. Demographic characteristics, risk factors for HIV infection, respiratory complications, and CD4+ lymphocyte counts were evaluated in these patients. RESULTS: All patients were males. The mean age was 35 years (age range: 15 to 63 years). Among 34 cases with available CD4+ lymphocyte count results, 70.6% had results <200 cells/mm(3). Nearly half the patients (47.7%) had respiratory symptoms. The most common pulmonary complications were cough (86.3%), sputum (71.6%), dyspnea (54.7%), and hemoptysis (10.5%). The most common diagnosis was pulmonary tuberculosis (27.1%), followed by other bacterial pneumonias (16.6%) and pneumocystis carinii pneumonia (4.5%). Intravenous drug users who had history of incarceration had the highest risk factors for Mycobacterium tuberculosis infection (59%), and other bacterial pneumonias (52%). CONCLUSION: Our study demonstrates that respiratory complications are highly frequent in HIV patients in Iran and that pulmonary tuberculosis is still a common complication in HIV infected patients, despite the availability of effective treatment. Results suggest the need for more effective preventive and prophylactic measures, wider use of antiretroviral treatment and effective chemotherapy for Iranian patients with HIV/AIDS.

Brucella endocarditis: a report from Iran.

Endocarditis is a rare focal complication of brucellosis but the most common cause of mortality. The diagnosis of the complications of endemic diseases is therefore important. We evaluated Brucella endocarditis cases in a teaching hospital in Iran between April 1998 and March 2006. Nine patients with a median age of 38.11 years were recorded, of whom seven (77.7%) were male. Underlying cardiopathy was present in three patients (33.3%). The median duration of the symptoms prior to diagnosis was 5.33 months. Endocarditis involved the aortic valve in six cases (66.6%), the mitral valve in two cases (22.2%) and the aortic valve plus the mitral valve in one case (11.1%). Serologic tests were positive in eight (88.8%) and blood culture was positive in two (22.2%). Aortic valve replacement surgery was undertaken for five patients (55.5%). One patient died due to arrhythmia. A high degree of suspicion is therefore necessary in order to ameliorate the course of Brucella endocarditis.
