The objective of this investigation was to determine whether Chlamydia pneumoniae was involved in an outbreak of respiratory disease among military recruits, 92 patients (average age 20.1 years) were included in the study if they had a sore throat or cough for more than 1 week. In addition to sore throat and cough, fatigue, headache, dyspnoea and vertigo were the most frequent symptoms. The patients received standard treatment with 100 mg of doxycycline b.i.d. for 14 days. In 38.8% of cases symptoms were alleviated after 1-2 weeks of treatment, and in 22.4% of cases after 2-3 weeks of treatment. Pretreatment throat washings and sera were sampled for Chlamydia. Sera were drawn for Chlamydia, Mycoplasma and adenovirus serology. Cell culture (Hep-2) and 3 different serological methods-microimmunofluorescence (MIF), enzyme immunoassay with a recombinant glycoconjugate antigen (r-EIA) and immunoperoxidase assay (IPA)-were used. Cell culture was found to have too low a sensitivity to be of diagnostic value. Acute infection was demonstrated in 13% by MIF IgM and in an additional 21% by MIF IgG (titre rises). Enzyme immunoassay IgM was found in 17% and IPA IgM in 19% of individuals without MIF IgM antibodies. Microimmunofluorescence was found to be the most useful test for serodiagnosis. The combination of serological methods showed that 40 out of 52 (76.9%) had an acute infection with possible chlamydial aetiology. In conclusion, methodological improvements are necessary for the aetiological diagnosis of chlamydial respiratory infections.

Acute infection is known to perturb psycho-neuroendocrine-immune (PNI) gene expression. Oligonucleotide microarrays were used to examine PNI gene expression in the peripheral blood of 13 subjects with infectious mononucleosis (IM). Novel peripheral blood gene expression activity was correlated with central-nervous-system-mediated symptoms including fatigue and sleep disturbance. Of note, expression of the MADS box transcription enhancer factor 2 polypeptide C (MEF2C) gene, previously implicated in skeletal muscle myogenesis, correlated with symptoms of musculo-skeletal pain and fatigue. Expression of the hypocretin/orexin receptor HCRTR2, which has been implicated in narcolepsy, correlated with sleep disturbance. And, VACHT, the vesicular acetylcholine transporter, was highly correlated with neurocognitive disturbance. The expression of both HCRTR2 and MEF2C in the peripheral blood was validated by reverse transcription PCR. Thus, investigation of the PNI response in peripheral blood may provide novel insights into the complex pathophysiology of centrally mediated disease states.

Although an estimated 1 million persons in the United States are chronically infected with hepatitis B virus, the prevalence of hepatitis B has declined since the implementation of a national vaccination program. Hepatitis B virus is transmitted in blood and secretions. Acute infection may cause nonspecific symptoms, such as fatigue, poor appetite, nausea, vomiting, abdominal pain, low-grade fever, jaundice, and dark urine; and clinical signs, such as hepatomegaly and splenomegaly. Fewer than 5 percent of adults acutely infected with hepatitis B virus progress to chronic infection. The diagnosis of hepatitis B virus infection requires the evaluation of the patient's blood for hepatitis B surface antigen, hepatitis B surface antibody, and hepatitis B core antibody. The goals of treatment for chronic hepatitis B virus infection are to reduce inflammation of the liver and to prevent complications by suppressing viral replication. Treatment options include pegylated interferon alfa-2a administered subcutaneously or oral antiviral agents (nucleotide reverse transcriptase inhibitors). Persons with chronic hepatitis B virus infection should be monitored for disease activity with liver enzyme tests and hepatitis B virus DNA levels; considered for liver biopsy; and entered into a surveillance program for hepatocellular carcinoma.

Acute infection with human immunodeficiency virus (HIV) is infrequently diagnosed, owing in large part to vague or non-specific symptoms. Among the most common of these symptoms are fever, fatigue, pharyngitis, lymphadenopathy, anorexia, arthralgia, myalgia, rash, and headache. Some patients seek no medical attention for such symptoms, and others recall no symptoms whatsoever. Physicians in all healthcare environments must maintain a high index of suspicion for HIV in the setting of these symptoms. For suspected acute infection, rapid serologic tests should be supplemented with assays of p24 antigen and/or HIV RNA viral load. We report here a case of acute HIV infection in a young man who presented with a negative rapid serologic test, as well as pancytopenia and transaminitis. We also review the epidemiology, transmission, diagnosis, and management of acute HIV infection.

Acute infection with Epstein-Barr virus (EBV) causes fever, fatigue and pharyngitis. Renal involvement in systemic EBV infections typically manifests as acute tubular necrosis or tubulointerstitial nephritis. Rarely, EBV infection causes nephrotic syndrome due to minimal change disease. A 22-year-old male with infectious mononucleosis (IM) presented with nephrotic syndrome. Renal biopsy showed minimal change disease with diffuse foot process effacement of the podocytes. Treatment with methylprednisone led to rapid and complete clinical remission. Minimal change nephropathy is a very rare manifestation of EBV infection and should be considered in patients with IM and proteinuria.
