Thirty-seven HIV-infected homosexual men with thrombocytopenia (less than 100 x 10(9)/l) received protein A immunoadsorption treatments to remove platelet-sensitizing immunoglobulin (Ig) G and circulating immune complexes (CIC) from plasma. Patients received an average of six treatments each, consisting of 250 ml plasma over a 3-week period. Clinical improvement in hemorrhagic symptoms associated with substantial increase in platelet counts was achieved in 18 patients. These responses were maintained over a median follow-up period of more than 7 months in 14 evaluable patients who were not lost to follow-up (three patients relapsed in 2 weeks and one received another therapy). Generally, moderate transient treatment-related side-effects included fever, musculoskeletal pain, chills and nausea. A transient serum sickness-like reaction was observed in seven patients, leading to termination of treatment in two. Clinical responses were associated with significant decreases in levels of platelet-sensitizing Ig, including CIC. Stimulation of broadly cross-reactive anti-antigen-binding fragment [F(ab)2], antibodies contributed to these responses. Protein A immunoadsorption is an effective alternative treatment for HIV-associated thrombocytopenia.

A clinical trial was conducted to determine the tolerance and toxicity of recombinant tumor necrosis factor (rTNF) and recombinant interferon gamma (rIFN-gamma) when administered concurrently by continuous intravenous infusion to 11 patients with the AIDS-related complex (ARC). In addition, HIV culture, p24 antigen levels, and CD4 positive lymphocytes were monitored to obtain preliminary evidence of antiviral and immunologic effects. Two 5-day treatment cycles were separated by a 9-day washout period. Two patients were entered at each dosage level and each patient received the two 5-day treatment cycles at two sequential dose levels ranging from 1 to 25 micrograms/m2. Two patients did not complete their second treatment cycle--one due to the development of a rash, the second due to central venous catheter discomfort. The occurrence of phlebitis with peripheral vein administration of these agents necessitated administration via central venous catheter. With the exception of a single patient who developed severe headache at the 25 micrograms/m2 dose, severe clinical toxicities were not observed. Fever, chills, headache, and myalgias were the most significant clinical toxicities observed and all were dose dependent. The percentage fall in total granulocytes was dose dependent and ranged from 17% at the 1 microgram/mm2 dose to 48% at both the 15 and 25 micrograms/mm2 dose levels. The mean nadir granulocyte count was 1694/mm3. No significant renal or hepatic toxicity was observed. Of 22 treatment cycles the CD4 cell number was increased in 11, unchanged in 7, and decreased in 4. The mean CD4 cell number did not change significantly (176 +/- 143/mm3 pretherapy versus 279 +/- 305/mm3 posttherapy).(ABSTRACT TRUNCATED AT 250 WORDS)

A study was conducted at the Ndola Central Hospital, Zambia, in 1987 to determine whether human immunodeficiency virus (HIV) infection increases the risk or severity of infection with falciparum malaria in patients aged 12 years and over. The 170 patients examined all presented with symptoms suggestive of malaria, including fever, chills, rigors, headaches, joint pains, myalgia, acute diarrhea, and vomiting. 67 (39%) were diagnosed as having falciparum malaria and 28 (17%) were positive for the HIV antibody. The prevalence of malarial parasitemia in patients with HIV antibodies was lower than that in patients without such antibodies (29% versus 42%, respectively), and differences in densities of parasites also failed to provide evidence of increased susceptibility to malaria in patients infected in HIV. There were no significant differences in antibody titers to P falciparum in patients who were positive for HIV antibody and in those who were negative, whether or not they had parasitemia. The earlier finding of a significant association between malaria and HIV infection is now believed attributable to false positive results with the 1st enzyme linked immunosorbent assays and to interpretation difficulties with the Western blot test. Of interest is the fact that 20 patients in this study had symptoms suggestive of malaria, but had negative results for parasites and positive results for HIV antibody. This indicates that many patients with HIV infection may be presenting with an illness clinically similar to malaria before acquired immunodeficiency syndrome (AIDS)-related complex or AIDS is recognizable.

Case of a 33-year-old female with AIDS who presented with fevers, chills, lower back pain and a large right hilar mass. Biopsy of the right paratracheal nodes revealed poorly differentiated non-small cell carcinoma with extensive necrosis. In patients infected with HIV the incidence of primary lung carcinoma is unknown. Despite these uncertainties, primary lung carcinoma must be considered in the differential diagnosis of young HIV-infected individuals presenting with intrathoracic radiographic abnormalities.

In June 1993, in Taiwan, a woman admitted to a local hospital with cough, fever, chills, and difficult breathing who tested positive for HIV-1 infection was transferred to Taipei Veterans General Hospital. In January 1985, at a provincial hospital, then 46 years old, she underwent an anterior total hysterectomy and bilateral salpingo-oophorectomy during which she received two units of whole blood. One of the blood donors was an AIDS patient who had been treated at the same hospital in 1991 and who had died in 1993. In the interim between hospitalizations, she had two episodes of herpes zoster infection, including oral ulcers diagnosed as herpetic gingivostomatitis, and an episode of oral candidiasis. Physicians at the Taipei Veterans General Hospital diagnosed oral candidiasis, herpes simplex type 1 virus infection forming ulcers on her lips, and Pneumocystis carinii pneumonia in June 1993. Her CD4 count was 0 and her CD8 count was 20%. Treatment consisted of intravenous (IV) trimethoprim/sulfamethoxazole (TMP/SMX) and oral zidovudine, fluconazole, and acyclovir. She continued this medication after discharge in August 1993. She was readmitted to Taipei Veterans General Hospital in February 1994 for blurred vision. She was diagnosed with cytomegalovirus retinitis. Her CD4 count was up to 1% and her CD8 count was down to 8%. The candidiasis infection had extended from her oral cavity to the esophageal mucosa. She was put on IV ganciclovir, TMP/SMX, and fluconazole. She was discharged 3 weeks after admission. Her condition deteriorated thereafter, resulting in her death in August 1994. Up until this study, this HIV/AIDS case was listed with 79 other HIV/AIDS patients as unknown cause. During the 8 years between HIV exposure and her diagnosis of AIDS, she had unprotected sexual intercourse with her husband. Neither the husband nor any of her four children have AIDS. Screening for HIV-1 in Taiwan began in January 1988. The authors urgently recommend that anyone who received a blood transfusion between 1984 and 1987 in Taiwan and who currently suffers repeated episodes of opportunistic infections undergo an HIV-1 blood test.

A 47-year-old man presented with a history of fever, chills and weight loss for 3 months. He had been treated for diabetes mellitus during the past 3 years. He developed high fever with abnormal liver function tests. Both Widal and Weil-Felix reactions were negative with normal roentgenogram of the chest. His anti-HIV tests were positive. The cultures from the blood and sputum yielded pure Sphingobacterium multivorum sensitive to sulfamethoxazole-trimethoprim, chloramphenicol, tetracycline, cefotaxime, ceftazidine and ceftriaxone. On the next day, the patient developed signs and symptoms of meningitis with the CSF containing chronic and acute inflammatory cells but revealed no growth on culture. The patient was treated with a combination of ceftriazone and trimethoprim-sulfamethoxazole but he died on the 6th day after admission. This patient was the fifth reported case infected with S.multivorum. It illustrates that this potentially pathogenic organism can cause septicemia in an immunodeficient patient.

We examined the relationship of somatic complaints to coping behaviors and mood states among 50 HIV-positive patients without AIDS. Although no patients fulfilled the DSM-III-R criteria for mood disorders including major depression, scores for depressive symptoms were significantly higher in the HIV-positive patients than in healthy persons. Although depressive symptoms in HIV patients may not be strong enough to warrant a psychiatric diagnosis of mood disorders, these patients may be prone to depressive symptoms. The HIV patients indicated a tendency toward somatic complaints more frequently than their healthy counterparts. The scores for depressive symptoms were significantly and positively correlated with scores for avoidance coping responses. The presence or absence of six complaints (i.e., general fatigue, abdominal distress, chest pain or discomfort, and numbness or chills) could be discriminated based on the score of avoidance coping responses. The results of this study suggest that avoidance coping responses associated with depressive symptoms accompany several somatic complaints in HIV patients without AIDS.

We describe five cases of parasitic sinusitis and otitis in patients infected with human immunodeficiency virus (HIV) and review 14 reported cases. The pathogens identified in our group of patients included agents such as Microsporidium, Cryptosporidium, and Acanthamoeba species. The clinical features common to these patients included a long history of HIV seropositivity associated with advanced immunosuppression and multiple opportunistic infections as well as long-standing local symptoms refractory to multiple courses of antibacterial agents. Symptoms often included fever and chills in addition to local tenderness and discharge. Invasive diagnostic procedures were necessary to obtain the final diagnosis and to initiate appropriate therapy. Although most patients responded at least partially to specific therapy, relapses and recurrences were frequent in patients who did not receive long-term suppressive therapy. The general outcome for HIV-infected patients with parasitic sinusitis and otitis was poor; however, deaths were generally associated with other complications of the underlying HIV infection.

We reviewed 71 consecutive patients with Streptococcus pneumoniae bacteremia. The patients were analyzed by age, sex, ethnic background, and clinical presentation. Laboratory data reviewed included a CBC count, electrolyte levels, liver function studies, chest radiograph, HIV status, a sputum culture and Gram's stain, and sensitivities for the S pneumoniae isolated. Modalities of therapy, response to treatment, and ultimate outcome were examined. Many of the patients with pneumococcal bacteremia did not have cough, fever, or chills. HIV positivity was a risk factor for pneumococcal infection although it was not associated with increased mortality. Mortality correlated with elderly status, leukopenia, and lack of fever. Many patients had symptoms suggestive of atypical pneumonia including myalgia and mental status change. Hyponatremia and hyperbilirubinemia were commonly noted.
