Evaluation of Non-Viral Surrogate Markers as Predictive Indicators for Monitoring Progression of Human Immunodeficiency Virus Infection: An Eight-Year Analysis in a Regional Center.

Suitable methods for clinical monitoring of HIV-infected patients are crucial in resource-poor settings. Demographic data, clinical staging, and laboratory findings for 112 asymptomatic subjects positive for HIV were assessed at the first admission and the last visit from 2002 to 2010. Cox regression analysis showed hemoglobin (Hb) (HR = 0.643, P = 0.021) to be a predictive indicator for disease progression, while CD4, CD8, and platelet counts showed low HRs, despite having significant probability values. Hb and total lymphocyte count (TLC) rapidly declined from stage II to III (10.9 and 29.6%, respectively). Reduced CD4 and platelet counts and Hb during stage I were associated with disease progression, and TLC was correlated with CD4 counts at the last follow-up (P < 0.001). However, WHO TLC cutoff of 1,200 cell/mm(3) had 26.1% sensitivity and 98.6% specificity. ROC curve analysis suggested that a TLC cutoff of 1,800 cell/mm(3) was more reliable in this region. Statistical analysis and data mining findings showed that Hb and TLC, and their rapid decline from stage II to III, in addition to reduced platelet count, could be valuable markers for a surrogate algorithm for monitoring of HIV-infected subjects and starting anti-viral therapy in the absence of sophisticated detection assays.

A 28-Year-Old Woman with Fever, Weight Loss, Pancytopenia, and Multiple Hepatosplenic and Bone Lesions.

Brucellosis is a systemic zoonotic infection that can involve any organ or system in the body. It may present with a broad spectrum of clinical manifestations. Considering such myriad presentations, brucellosis should always be considered in the differential diagnosis of any febrile illness in a compatible epidemiological context. Here, we report a rare presentation of acute brucellosis with multifocal osteomyelitis and hepatosplenic lesions.

HIV: An Epidemiologic study on Head and Neck Involvement in 50 Patients.

INTRODUCTION: Acquired immunodeficiency syndrome (AIDS) is a worldwide infection. Because of the vast array of manifestations of AIDS and its many atypical presentations, it is becoming increasingly challenging for clinicians to accurately diagnose new lesions. MATERIALS AND METHODS: In a descriptive cross-sectional study conducted from 2007 to 2010, 50 patients with a proven human immunodeficiency virus (HIV) infection were evaluated. Based on the findings of a physical examination and paraclinic tests, HIV signs and symptoms were recorded. RESULTS: The mean (range) age of the patients was 35.45 ±5.24 (5-55) years. Forty-two (84%) cases were male and eight were female. The mean duration of carrying the virus was 4.51 ±1.03 years. Oral manifestations were the most common (94%), followed by rhinologic (88%), otologic (66%), and finally neck (44%) manifestations. CONCLUSION: Head and neck presentations are very common in HIV patients; therefore otolaryngologists, as the first physicians who may encounter such patients, should be aware of this condition.

Brucellar psychosis.

Brucellosis is the most common worldwide zoonotic infection of which psychosis is a rare feature of this disease. Brucellar psychosis should be considered in a patient with unexplained, nonspecific psychological complaints. Its timely diagnosis relies on special attention to the epidemiologic profile of the patient for a possible exposure to the brucella species. This article has presented three cases of brucellar psychosis initially misdiagnosed because the risk factors which made them at risk for the disease were ignored.

Disseminated tuberculosis in a kidney transplant patient: Diagnostic significance of reversed circadian temperature rhythm.

Presently, clinicians often forget important aspects of fever patterns. This study presents the case of disseminated tuberculosis in a 64-year-old man whose chief complaint was morning fever. He was a kidney transplant patient and presented with productive cough, reverse fever pattern and a nodular pattern in chest radiograph. Clinicians should suspect disseminated tuberculosis in patients who present with reverse fever pattern, especially with compatible radiographic findings.

Isolated tricuspid valve endocarditis.

We present two non-HIV-infected patients with isolated native non-rheumatic tricuspid valve endocarditis who were not intravenous drug abusers. The patients presented with fever and chills. Plain radiography or high-resolution computed tomography of the chest revealed consolidation or infiltrate of the left parenchyma in both patients. Large vegetation located on the tricuspid leaflets was detected by transesophageal echocardiography. Staphylococcus aureus grew in two out of three blood cultures for one patient. Tricuspid valve endocarditis imitates illnesses with fever and pulmonary symptoms or signs of acute or chronic onset, and might be present even without abnormal chest X-rays or intravenous drug addiction.
